LED Lighting Power Controller
Jump to Page Section:
Overview
Description
R2A20135 is LED lighting controller IC with dimming function. High accuracy LED current feed-back system makes more efficient LED performance. With non-Isolation step-down control makes it possible to reduce external parts and realize high power factor and efficiency. Moreover, this IC builds in the dimming function and can control many types dimming mode such as Triac, PWM, and DC dimming. Switching mode can chosen Zero Current detect Mode or Fixed Frequency Mode according to the required features. By the Constant On Time control, both modes have power factor correct function. Zero Current detect Mode is better performance for noise immunity, and Fixed Frequency Mode is for power factor correction and THD.
