The LNK6776K-TL is part of the LinkSwitch-HP family of flyback power supply ICs. It incorporates a primary-side regulated (PSR) controller and a high-voltage 725V power MOSFET in a single eSOP-12B package. The device is optimized for constant voltage (CV) operation and provides high efficiency across the full load range using multi-mode PWM control. It includes extensive protection features such as output short-circuit, overload, overvoltage (hysteretic or latching), and accurate thermal shutdown. Its design eliminates the need for an optocoupler and all secondary-side control circuitry, simplifying AC/DC power supply designs.
