UCL2300 Datasheet | Unisonic Technologies

UNISONIC TECHNOLOGIES CO., LTD Advance LINEAR INTEGRATED CIRCUIT PSR SINGLE-STAGE APFC OFFLINE LED DRIVER - DESCRIPTION The UTC UCL2300 is a high precision primary-side regulation controller with single stage Active PFC, specially designed for universal input offline flyback or buck-boost constant current LED lighting. The controller with on-chip PFC circuit achieves high power factor and low THD. Operating in critical conduction mode, the power MOSFET switching loss is reduced and the inductor is fully utilized. The UTC UCL2300 adopts proprietary primary side current sensing scheme. It can precisely control the LED current without secondary side sense and feedback circuits....
