1 IntroducTIon   The document describes a non-isolated, high power factor (PF), TRIAC dimmable LED   driver designed to drive a nominal LED string voltage of 48 V at 120 mA from an input   voltage range of 185 VAC to 265 VAC (50 Hz typical)。 The LED driver uTIlizes the   LYT4322E from the LYTSwitch-4 family of ICs.   The topology used is a single-stage non-isolated buck-boost that provides high power   factor, constant current regulaTIon, and delivers excellent dimming performance.   This document contains the LED driver specificaTIon, schematic, PCB details, bill of   materials, transformer documentation and typical performance characteristics.
