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 pliance. 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 in the RSET for better efficiency. With its internal 2A, 100mΩ NMOS switch, the device can provide high efficiency even at heavy load. The device switches at a 1MHz constant frequency, allowing for the...
