L6565 is a current-mode primary controller IC, specifically designed to build offline Quasi-resonant ZVS (Zero Voltage Switching at switch turn-on) fly- back converters.
The L6565 is a current‑mode primary controller IC designed for offline quasi‑resonant flyback converters. It features line‑voltage feed‑forward, ultra‑low start‑up and quiescent currents, a disable function, and pulse‑by‑pulse over‑current protection.
The document provides pin descriptions, electrical and thermal specifications, mechanical outline dimensions, and application notes for implementing the device in TV/monitor SMPS, AC‑DC adapters, printers, fax machines, and other digital consumer products.
