NCP1013AP065

AC DC Converters, Offline Switchers Overview

The NCP1013AP065 is a monolithic switcher from the onsemi NCP101X series, integrating a fixed-frequency current-mode controller with a 700 V MOSFET. It operates at a fixed frequency of 65 kHz and features a typical RDSon of 22 Ω. The device includes dynamic self-supply (DSS), eliminating the need for an auxiliary winding, and incorporates a 1.0 ms soft-start timer. Protection mechanisms include latched overvoltage protection, auto-recovery output short-circuit protection, and internal thermal shutdown. It is housed in a PDIP-7 package.
