DESCRIPTION

The UTC UC4107 is a two-stage controller with dual gate
drivers consist of a Boost converter and a Buck converter. The
advantage of the two-stage topology is highly compatible with
Electronic Transformer in MR16/AR111 lighting market field
applications.
The UTC UC4107 is equipped with dual output gate drivers for
external power MOSFETs, suitable for higher power applications.
