Description

The KAB3403T/DN is a monolithic step-up DC/DC converter specifically designed to drive white LEDs with a constant current from Li-ion cell.

Relative large 320mV feedback voltage & it s high accuracy help you setting LED current with a external resistor.

KAB3403T/DN is available in a extremely low profile & small TS-6 package.

A 10 H inductor is sufficient for most application.
