≤3.3 V

Note A:

All characteristic data in the above graphs has been develped from actual products tested at 25 °C. This data is considered typical for the ISR.

Note B:

SOA curves represent operating conditions at which internal components are at or below manufacturer’s maximum rated operating temperatures.

Notes:

(1) The PT6620 Series requires a 330 µF(output) and 100 µF(input) electrolytic capacitors for proper operation in all applications.

(2) ISR will operate down to no load with reduced specifications

(3) See safe Operating Area curves or contact the factory for the appropriate derating.
