RT8479B driver equivalent, two-stage hysteretic led driver.
* Two-Stage Topology (Boost + Buck)
* Dual MOSFETs Inside
* Wide Input Voltage Range : 4.5V to 36V
* Excellent Power Factor
* Programmable Boost Outpu.
The first stage is a Boost converter for constant voltage output with inductor peak current over-current protection. Th.
The RT8479B 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 .
