TECHNICAL DATA
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.
FEATURES
Inherently Matched LED Current.
High Efficiency : 87% (max.)
Built in a open circuits protection for the LEDs fail.
Drives Up to Five LEDs
Built in a N-channel MOSFET Switch.
Fast 1.1MHz(typ.) Switching Frequency.
Wide Dimming control range : 12%~100%.
Automatic Soft-Start
Bulit in OVD (Over voltage protection.)
Extremely low height & small Packaging.
APPLICATIONS
Celluar Phones
Smart Phones
PDAs
Digital Cameras
MP3 Players, Color Displays
