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 typically the input voltage, Vin. Refer to the application notes 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. See application notes.
(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 see the applicable package outline drawing.
Input/Output Capacitors: For proper operation in all applications, the PT6725 series requires a 1,000µF input capacitor (Cin) with a minimum 1.6Arms ripple current
rating. And a 330µF output capacitor (Cout) with a maximum ESR of 50mΩ at 100kHz. For transient or dynamic load applications, additional output capacitance may be
necessary. The maximum allowable output capacitance is 15,000µF. 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 6.5ADC with a typical value of 1µH.
