Notes:
(1) The PT6640 Series requires a 330F(output) and 560F(input) electrolytic capacitors for proper operation in all applications.
(2) See Safe Operating Area curves or call the factory for guidance on thermal derating.
Efficiency vs Output Current
Characteristic Curves @12.0V Vin (See Note A)
Safe Operating Area Curves (See Note B)
Power Dissipation vs Output Current
Ripple vs Output Current
Note A:
Characteristic data has been developed from actual products tested at 25°C. This data is considered typical data for the DC-DC Converter.
Note B:
SOA curves represent operating conditions at which internal components are at or below manufacturer’s maximum rated operating temperatures.
