高功率因数和低纹波电流
The iW3626 integrates high power-factor (PF), low output ripple and low total harmonic distortion (THD) in a single-stage SSL LED driver for isolated and non-isolated applications up to 10W for 60W-equivalent non-dimmable LED replacement bulbs.
IW3626集成了独特的混合控制方案，可配置的可配置功率因数> 0.7和> 0.9，以管理PF和LED输出电流纹波之间的权衡。这种独特的功能可以从低成本解决方案启用高PF和低纹波。
The iW3626 reduces the BOM cost and solution size by incorporating Dialog’s proprietary PrimAccurate™ technology, eliminating the need for a secondary side regulator and optical feedback isolator. Dialog's 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 BJTs, so there is no need for high-voltage electrolytic capacitors.
