Datasheet	RT8476 Datasheet

The RT8476 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 two-stage topology is highly compatible 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.
