概要
説明
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.
