Description
The PT6715 series of power modules are a 13-A rated integrated switching regulator (ISR), housed in a 17-pin space saving solderable copper package. These modules will operate off either a 5V or 3.3V input power bus to provide a highperformance low-voltage power source for the industry's latest high-speed, DSPs, µPs, and bus drivers. This allows for the easy integration of these new low-voltage ICs into existing 3.3V or 5V systems without re-designing the central power supply. The series includes the standard output bus voltage options, ranging from 1.0V to 3.3V. Each output voltage option has a limited adjust range. Features include a Standby (On/Off) function, a differential output Remote Sense, and short circuit protection. The modules are available in both throughhole and surface mount configurations.

Notes: (1) The ISR will operate at no load with reduced specifications. (2) If the remote sense feature is not being used, connect the Remote Sense Gnd (pin 7) to GND (pin 8) for optimum output voltage accuracy. (3) The STBY* control (pin 2) has an internal pull-up and if it is left open circuit the module will operate when input power is applied. The open-circuit voltage is typcially 12.6V, and maybe as high as 15V. Consult the related application note for other interface considerations. (4) For operation below 0°C, Cin and Cout must have stable characteristics. Use either low ESR tantalum or Oscon® capacitors. (5) See Safe Operating Area curves or contact the factory for the appropriate derating. (6) The case pins on through-hole package types (suffixes N & A) must be soldered. For more information consult the applicable package outline drawing. Input/Output Capacitors: The PT6715 series requires a 1,000µF electrolytic (or tantalum) capacitor at the input and 330µF at the output for proper operation in all applications. In addition, the input capacitance, Cin, must be rated for a minimum of 2Arms of ripple current. For transient or dynamic load applications additional capacitance may be necessary. For more information consult the related application note on capacitor recommendations. Input Inductor: An input filter inductor is optioinal for most applications. The inductor must be sized to handle 10ADC with a typical value of 1µH.
