描述 Description

White LED Step-Up Converter

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 10H inductor is sufficient for most application.FEATURES
Inherently Matched LED Current.
