LNK6408E

AC DC Converters, Offline Switchers Overview

The LNK6408E is a high-voltage integrated switch from the LinkSwitch-VP family by Power Integrations. It operates with an input voltage range of 85–265 VAC and delivers up to 13 W of output power using a flyback topology. The device integrates a 700 V MOSFET, control logic, high-voltage current source, oscillator, thermal shutdown, and cycle-by-cycle current limit. Key features include adaptive burst mode for low no-load power consumption, frequency jittering for EMI reduction, and primary-side regulation eliminating optocouplers.
