Notes: (1) The PT6600 series requires two 330µF electrolytic capacitors (input and output) for proper operation in all applications. The input capacitance must be rated for a minimum of

1.1Arms of ripple current. See the application note, PT6500/6600 Series Capacitor Recommendations.

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

(4) See Safe Operating Curves, or contact the factory for the appropriate derating.
