Application note

L6585DE combo IC

Introduction

The modern requirements for fluorescent lamp electronics ballast concerns both efficiency

of the drivers and safety aspects.

The L6585DE offers the designer a high performance PFC stage, high capability half bridge

high voltage drivers, a fully programmable control and an enhanced set of protections.
