LNK6667V

AC DC Converters, Offline Switchers Overview

The LNK6667V is a LinkSwitch-HP family offline switcher integrating a primary-side regulated (PSR) controller and a 650 V power MOSFET in an eDIP-12B package. It operates in continuous conduction mode (CCM) with a switching frequency of 120 kHz to 136 kHz and a maximum duty cycle of 64%. The device supports isolated flyback topologies, features brown-in/brown-out detection, and includes programmable shutdown delay, remote on/off, and fast AC reset options. It provides comprehensive protection including output overvoltage, undervoltage, thermal, and short-circuit protection.
