RT8479C
Two-Stage Hysteretic LED Driver with Internal MOSFETs
General 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 compatible 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 over-current protection.
The second stage is a Buck converter for constant output current by typical constant peak current regulation.
The RT8479C is equipped with dual output gate drivers for i...
