RS2332SP - High-Voltage Start-Up Primary Side LED Controller with Active PFC - PTC 数据手册 ( 数据表 )

DESCRIPTION
The RS2332 integrates 600V ultra high voltage startup circuit reduces the total power consumption to provide a high efficiency solution for lighting applications and it is a single-power stage, isolated, primary-side-control offline LED lighting controller that achieves high power factor in a single SOP-8 package. The proprietary real-current control method can control the LED current accurately from the primary side information. It can significantly simplify the LED lighting system design by eliminating the secondary side feedback components and the opto-coupler.
