Overview

Single Cell 350mA, Dual Cell 1A LED Driver CE9401 Series  INTRODUCTION: The CE9401 provides a constant current drive for 1W or 3W LED applications.

It is a high efficiency boost converter that operates from 1 or 2 NiMH or alkaline cells and generates 350mA/1A of constant current with up to 4V of compliance.

The LED current can be programmed by the external current sense resistor, RSET, connected between the feedback pin (FB) and ground.
