NCP1014AP065G

AC DC Converters, Offline Switchers Overview

The NCP1014AP065G is a self-supplied monolithic switcher for low standby-power offline SMPS. It integrates a fixed-frequency current-mode controller and a 700 V MOSFET with typical RDSon of 11Ω and 22Ω. The device operates at 65 kHz, 100 kHz, or 130 kHz and features skip-cycle operation to minimize acoustic noise. It includes internal 1.0 ms soft-start, frequency jittering for EMI improvement, and auto-recovery short-circuit protection. Housed in a PDIP-8 package, it supports Dynamic Self-Supply without an auxiliary winding.
