T6309B - Micropower Step-up DC/DC Converter

Datasheet Summary

Description

The T6309B is a step-up DC/DC converter that drives LED with a constant current.

The device can driver up to 3 series LEDs from a single-cell Li-Ion battery.

Series connection of the LEDs provides constant LED current that results in uniform brightness.
