LED Lighting Power Controller
Jump to Page Section:
Overview
Description
R2A20134SP is a LED lighting controller IC. Control method is selectable for each system demand, fixed frequency or zero current detection mode. High accuracy LED current feed-back system makes more efficient LED performance. Critical Conduction Mode PFC control realizes high power factor and zero current switching. And Peak Current Mode makes it possible to reduce external parts and realize low system cost.
Features
- Absolute Maximum Ratings Supply voltage Vcc: 24 V Junction temperature Tj: –40 to +150°C
- Electrical characteristics UVLO operation start voltage VH: 12 V ± 0.8 V UVLO operation shutdown voltage VL: 9.2 V ± 0.7 V UVLO hysteresis voltage Hysuvl: 2.8 V ± 0.7 V
- Functions Selectable for each targeted system, 1. Zero current detection mode (When Rrt is connected by GND) 2. Fixed frequency mode (When Rrt is connected by Vref) Adjustable for Switching frequency (When Rrt is connected by Vref) Overcurrent protection Package lineup: Pb-free SOP-8 (JEDEC)
