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.
