RT8476A Description

The RT8476A is a two-stage controller with dual gate drivers consist of a Boost converter (first stage) and a Buck converter (second stage). The advantage of the twostage topology is highly patible with ET (Electronic Transformer) in MR16 / AR111 lighting market field applications. The first stage is a Boost converter for constant voltage output with inductor peak current over-current protection.
