iW3626中文资料Single-Stage, 10W Offline SSL LED Driver with High Power Factor and Low Ripple数据手册Renesas规格书

描述 Description

The iW3626 integrates high power factor (PF), low output ripple and low total harmonic distortion (THD) in a single-stage solid-state lighting (SSL) LED driver for isolated and non-isolated applications up to 10W for 60W-equivalent non-dimmable LED replacement bulbs.

The iW3626 integrates a unique hybrid control scheme with a configurable power factor between >0.7 and >0.9 to manage the trade-off between PF and LED output current ripple. This unique feature enables high PF and low ripple from a low-cost solution.

The iW3626 reduces the BOM cost and solution size by incorporating Renesas' proprietary PrimAccurate™ technology, eliminating the need for a secondary side regulator and optical feedback isolator. Renesas' advanced technology allows for the functionality and performance of an 8-pin part in a small SOT23 6-pin package. It also uses lower-cost bipolar junction transistors (BJTs), so there is no need for high-voltage electrolytic capacitors.
