NCP1071P065G Description

The NCP1071P065G product integrates a fixed frequency current mode controller with a 700 V MOSFET. Available in a PDIP−7 package, the NCP1071P065G offers a high level of integration, including soft−start, frequency−jittering, short−circuit protection, skip−cycle, a maximum peak current set point, ramp compensation, and a Dynamic Self−Supply (eliminating the need for an auxiliary winding).

NCP1071P065G Features

Built−in 700 V MOSFET with RDS(on) of 4.7  (NCP1076/77) / 11  (NCP1072/75) / 22  (NCP1070/71)

Large Creepage Distance Between High−voltage Pins

Current−Mode Fixed Frequency Operation – 65 / 100 / 130 kHz
