Description
The PT5400 ExcaliburTM power modules are a series of high-performance integrated switching regulators (ISRs) based on TI's SWIFT (Switcher With Integrated FET Technology) regulator ICs. These ready-to-use modules are rated for up to 6 A of output current from input voltages as low as 3.1 V, providing a convenient step-down power source for the industry's latest high-performance DSPs and microprocessors. The series includes output voltage options as low as 1.0 VDC. The PT5400 modules are packaged in a 5-pin thermally efficient copper case, which offers the advantage of solderability along with a small footprint (0.355 in, suffix `N'). Both through-hole and surface mount pin configurations are available. The product features external output voltage adjustment, an on/off inhibit function, short circuit protection, and thermal shutdown. A 100-F input capacitor is required for proper operation.

PT5400 Series
Operating Features of the PT5400 SWIFTTM Series of Power Modules
Under-Voltage Lockout (UVLO)
The PT5400 SWIFT series of power modules incorporate an under-voltage lockout (UVLO) function. The UVLO function provides a clean transition during powerup and power-down, allowing the regulator to tolerate a slowly rising input voltage. The UVLO prevents operation of the module until the input voltage has risen above 2.95 V. Below this threshold the status of the inhibit control pin is overriden, and the module will not produce an output. When the input voltage rises above this threshold, the output status of the module is determined by the inhibit control pin. If the inhibit control is open-circuit (not grounded), the module will automatically power up. The UVLO circuit has approximately 0.16 V of hysteresis, and will completely turn off the module when a falling input voltage drops below about 2.8 V. (Note: Even though the applied input voltage may be above the UVLO threshold, operation to the published specifications requires that the input voltage be at or above the minimum specified for each model in the series. This ensures that the output voltage of the module is in regulation.) If desired, both time periods can be lengthened with the addition of a low value capacitor between the Inhibit control (pin 1) and the COM (pin 3). For a given value of external capacitance, Cinh, the formulas for calculating the approximate effect on td and t(SS) are given below. td t(SS)  (Cinh + 0.047 F) x 1.2 V 5 A  (Cinh + 0.047 F) x 0.7 V 5 A
Note: The capacitor should be placed as close to the regulator as possible. Adding 0.047 F of external capacitance to the Inhibit pin approximately doubles the value of td and t(SS).
Current Limit Protection
The output current limit feature is one of two fault protection mechanisms built into the PT5400 modules. Its purpose is to protect both the module and input source against the occurance of a load fault, thereby isolating the fault and preventing it from propagating to other parts of the power system. The PT5400 regulators sense the current switched by the series (high-side) power MOSFET. The circuit implements a continuous current limit characteristic. Upon the removal of the fault the output voltage will promptly recover, and the module will return to normal operation. A current limit condition will also increase the module's power dissipation, which may cause the temperature of the internal components to significantly rise. If the condition persists, the module may begin to cycle in and out of thermal shutdown.
Soft-Start Power Up
Following either the application of a valid input source voltage, or the removal of a ground signal to the inhibit control pin (with input power applied), the module will initiate a soft-start power up. The soft start has two effects on the start-up characteristic. It introduces a short time delay prior to the start-up of the output voltage, and also slows the rate at which the output voltage rises. Figure 1-1 shows the power-up characteristic of a PT5404 (1.8 V). In this example the delay time, td, is measured from the point at which the input voltage rises above 2.95 V (the UVLO threshold), to the point that the output voltage starts to rise. The time period t(SS) is the rise time of the output voltage ramp. The value of td and t(SS) are are approximately 10 ms and 7.5 ms respectively.
Figure 1-1; Soft-Start Characteristic and Timing
HORIZ SCALE: 5ms/Div
Thermal Shutdown
Thermal shutdown is the second fault protection mechanism and protects the module's internal circuitry against excessively high temperatures. A rise in the temperature of the internal circuitry may be the result of a drop in airflow, a high ambient temperature, or a sustained overcurrent load fault. If the junction temperature of the internal components exceed 150 C, the module will shutdown. Once in thermal shutdown, the regulator is disabled and the output voltage is reduced to zero. The recovery is automatic and begins with a soft-start power up. Recovery occurs when the the sensed temperature decreases 10 C below the trip point.

Capacitor Recommendations for the PT5400 SWIFTTM Series of Power Modules
Input Capacitors The recommended input capacitance is determined by 100 F minimum capacitance, 300 mA (rms) minimum ripple current rating, and less than 300 m equivalent series resistance (ESR). The ripple current rating, ESR, and operating temperature are the major considerations when selecting the input capacitor. It is recommended that tantalum capacitors have a minimum voltage rating of at least twice the working voltage, including the ac ripple. This is necessary to insure reliability with 3.3-V input voltage bus applications. Output Capacitors (optional) The ESR of the output bulk (non-ceramic) capacitance must be between 10 m ESR 200 m. Electrolytic capacitors have poor ripple performance at frequencies greater than 400 kHz but excellent low frequency transient response. Above the ripple frequency, ceramic decoupling capacitors are recommended to improve the transient response and reduce any high frequency noise
components apparent during higher current excursions. A maximum of 100 F ceramic capacitance may be added to the output bus. Tantalum/ Ceramic Capacitors Tantalum capacitors are acceptable on the output bus. Tantalum, Os-con(R), or ceramic capacitor types are recommended for applications where ambient temperatures fall below 0 C. Ceramic capacitors may be used instead of electrolytic types on both the input and output bus. The input bus must have at least the minimum amount of capacitance. For the output bus the total amount of ceramic capacitance should be limited to 100 F. Capacitor Tables Table 2-1 identifies vendors with acceptable ESR and maximum allowable ripple current (rms) ratings. Capacitors recommended for the output are identified under the Output Bus column with the required quantity. This is not an extensive capacitor list. Capacitors from other vendors are available with comparable specifications. Those listed are for guidance. The RMS ripple current rating and ESR (at 100 kHz) are critical parameters necessary to insure both optimum regulator performance and long capacitor life.

Application Notes
PT5400 Series
Using the Inhibit Control of the PT5400 SWIFTTM Series of Power Modules
For applications requiring output voltage On/Off control, the PT5400 series of SWIFT power modules incorporate an inhibit function. This function can be used wherever there is a requirement for the module to be switched off. The On/Off function is provided by the Inhibit (pin 1) control. The ISR functions normally with Pin 1 open-circuit, providing a regulated output whenever a valid source voltage is applied to Vin, (pin 2). When a low-level2 ground signal is applied to pin 1, the regulator output will be disabled. Figure 3-1 shows an application schematic, which details the typical use of the Inhibit function. Note the discrete transistor (Q1). The Inhibit control has its own internal pull-up to +Vin potential. An open-collector or open-drain device is required to control this input 1. The Inhibit pin control thresholds are given in Table 3-1.
Table 3-1; Inhibit Control Requirements
Parameter Enable (VIH) Disable (VIL) Min Vin - 0.5 -0.2V Max
HORIZ SCALE: 5ms/Div
Turn-On Time: In the circuit of Figure 3-1, turning Q1 on applies a low-voltage to the Inhibit control (pin 1) and disables the regulator output. Correspondingly, turning Q 1 off allows the ISR to execute a soft-start power up. The soft-start power up consists of a short delay, t d, followed by a period, t(SS), in which the output voltage rises from zero to its full regulation voltage. (See the section on Soft-Start Power Up). The module produces a fully regulated output voltage within 25msec. Figure 3-2 shows the typical rise in both output voltage and input current for a PT5404 (1.8V), following the turn-off of Q1. The turn off of Q1 corresponds to the drop in the Q1 Vgs waveform. The time periods, td and t(SS), are indicated. The waveforms were measured with a 5Vdc input voltage, and 0.7- resistive load.

PT5400 Series
Adjusting the Output Voltage of the PT5400 Series of 6-A SWIFT Power Modules
The output voltage of the PT5400 series of SWIFT power modules may be adjusted higher or lower than the factory trimmed pre-set voltage with the addition of a single external resistor. Table 4-1 gives the allowable adjustment range for each model of the series as Va (min) and Va (max). Adjust Up: An increase in the output voltage is obtained by adding a resistor R2, between pin 5 (Vo adj) and pin 3 (GND). Adjust Down: pin 4 (Vout). Add a resistor (R1), between pin 5 (Vo adj) and The values of (R1) [adjust down], and R2 [adjust up], can either be calculated using the following formulas, or may be looked up from the range of values in Table 4-2. Refer to Figure 4-1 for the placement of the required resistor; either (R1) or R2 as appropriate. (R1) R2 Where:

Notes: 1. Use a 1% (or better) tolerance resistor in either the (R1) or R2 location. Place the resistor as close to the ISR as possible. 2. Never connect capacitors from Vo adj to either GND or Vout. Any capacitance added to the Vo adjust pin will affect the stability of the ISR. 3. For each model, adjustments to the output voltage may place additional limits on the minimum input voltage. The revised minimum input voltage must comply with the following requirement. Vin(min) = (Va + 1.1) V or as specified in the data sheet, whichever is greater. 4. The PT5408 operates only from a 3.3-V input bus. The limited input to output voltage differential of this model does not allow it to be adjusted higher than its trimmed output voltage.
