INTRODUCTION
The CE9910 is a 1.
5MHz constant frequency, slope compensated current mode PWM synchronous step-down converter that delivers a regulated output current.
The internal synchronous switch increases efficiency and eliminates the need for an external
Schottky diode.
The CE9910 is targeted to be used for driving loads up to 1A from a single cell Lithium-Ion battery.
The LED current can be programmed by the external current sense resistor.
A low 100mV feedback voltage reduces the power loss for better efficiency.
