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. (3) For operation below 0°C, use tantalum capacitors for CIN and C OUT. (4) See Safe Operating Curves, or contact the factory for the appropriate derating.
