Notes: (1) The ISR will operate down to no load with reduced specifications.
(2) This is a typical value only. The switching frequency will vary with input voltage.
(3) The Inhibit control (pin 1) 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 is recommended to control this input. Ensure an On/Off transition time of
≤10s. See application notes for more information.
(4) The PT5520 Series requires a 100F electrolytic or tantalum output capacitor for proper operation in all applications.
(5) For operation below 0°C, the output capacitor C2 must have stable characteristics. Use either a low ESR tantalum or Oscon capacitor.
(6) See SOA curves or consult factory for the appropriate derating.
(7) The case pins on the through-hole package types (suffixes N & A) must be soldered. For more information see the applicable package outline drawing.
