BW6562A High PFC LED Driver
Features
Product Description
The BW6562A is a cost effective high performance transition-mode (TM) power factor correction (PFC) controller IC optimized for high PFC LED driver, battery chargers and pre-regulator applications. The BW6562A integrates an internal start-up timer, a highly linear multiplier with Total Harmonics Distortion (THD) optimizer for near unity power factor, a Zero Current Detector (ZCD) to ensure transition-mode operation and a current sensing comparator with built-in leading edge blanking. With ZCD control, power MOSFET is always turned on with zero inductor current. Consequently, transition-mode control achieves lower switching loss and reduced noise.
