Notes:
(1) ISR-will operate down to no load with reduced specifications.
(2) If the remote sense ground is not used, pin 13 must be connected to pin 14 for optimal output voltage accuracy.
(3) The Standby control (pin 8) has an internal pull-up, and if left open-circuit the module will operate when input power is applied. A small low-leakage (<100nA)
MOSFET must be used to control this input. The open-circuit voltage is less than 10V. See application notes for further information.
(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.
(6) The case pins on the through-hole package types (suffixes N & A) must be soldered. For more information see the applicable package outline drawing.
External Capacitors: The PT6722 requires a minimum ouput capacitance of 330F, and a minimum input capacitance of 1,000F for proper operation. The input
capacitance must be rated for a minimum of 1.6Arms of ripple current. For transient or dynamic load applications, additional input and output capacitance may be
required.The maximum allowable output capacitance is 15,000F. For more information refer to the application note regarding capacitor selection for this product.
Input Inductor: An input filter inductor is optional for most applications. The inductor must be sized to handle 3ADC with a typical value of 1H.
