The iW3628 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, 20W, non-dimmable LED replacement bulb applications.
The iW3628 integrates a unique hybrid control scheme that allows designers to configure PF 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 iW3628 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. It also uses lower-cost bipolar junction transistors (BJTs) so there is no need for high-voltage electrolytic capacitors.
