General Description

The GS5903 is designed to drive up to 10 white LEDs in series with a 3.6V cell Li-Ion battery.

It works as a boost converter using current mode, 1.2MHz PWM frequency with the measure of an external current sense resistor to regulate the LED current.

In order to minimize the power loss and keep the efficiency, the feedback voltage is designed as low as 300mV.
