TECHNICAL DATA
KAB3403T/DN
BICD LINEAR INTEGRATED CIRCUIT
Revision No : 0
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 10 H inductor is sufficient for most application.
