LNK6773K [Power Integrations]

The LinkSwitch-HP family integrates a controller and high-voltage power MOSFET into a single package. It features multi-mode control for maximum efficiency across the full load range, with no-load consumption below 30 mW at 230 VAC. The device eliminates the need for optocouplers and secondary control circuitry, simplifying power supply designs while achieving ±5% output voltage tolerance. It operates at 132 kHz to reduce transformer size and includes programmable current limit, frequency jittering for EMI reduction, and integrated soft-start. Protection features include auto-restart, output short-circuit protection, overload/over-current protection, overvoltage protection, line brown-in/out protection, line overvoltage shutdown, and accurate thermal shutdown. Package options include eSIP-7C, eSOP-12B, and eDIP-12B with exposed pads for thermal management.
