RT8479C Description
The RT8479C is a two-stage controller with dual MOSFETs and consists of a Boost converter (first stage) and a Buck converter (second stage). The advantage of two-stage topology is highly patible with ET (Electronic Transformer) and extremely high Power Factor performance in MR16 / AR111 lighting market fields applications. The first stage is a Boost converter for constant voltage output with inductor peak current...
