CE9401 Single Cell 350mA / Dual Cell 1A LED Driver

Switch Pin. Connect inductor between SW and VIN. A Schottky diode is connected between SW and VOUT. Trace connections made to the inductor and schottky diode should be minimized to reduce power dissipation and increase overall efficiency. Keep these PCB trace lengths as short and wide as possible to.

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. A low 95mV feedback voltage reduces the power loss i.
