L8565 Datasheet | Unisonic Technologies

UNISONIC TECHNOLOGIES CO., LTD Preliminary LINEAR INTEGRATED CIRCUIT HIGH PERFORMANCE POWER FACTOR CORRECTION CONTROLLER IN CONTINUOUS CONDUCTION MODE - DESCRIPTION The UTC L8565 is a wide input range controller integrated circuit for active power factor correction. The circuit is designed for boost PFC application, and requires reduced external ponent count. Its power supply is remended to be provided by an external auxiliary supply which will switch on and off the IC. The circuit operates in the continuous conduction mode under average current, and in discontinuous conduction mode only in light load condition. The switching frequency can be set with the external...
