WHITE LED STEP-UP

CONVERTER

DESCRIPTION

The UTC L5100 is a STEP-UP DC/DC Converter and

designed for driving white LEDs with a constant current. It

can drive several LEDs in series by a Li-Ion cell. UTC L5100

switches at a high frequency 1.2MHz, so it can allowing the

use of tiny external components. The output capacitor can be

as small as 0.22µF, saving space and cost compare with

alternative other solutions. The low 95mV feedback voltage

minimizes power loss in the current setting resistor can have

better efficiency.

FEATURES

* Drives Up to Four LEDs from a 3.2V Supply

* Drives Up to Six LEDs from a 5V Supply

* 36V Rugged Bipolar Switch

* 1.2MHz Switching Frequency

* Uses Tiny 1mm Tall Inductors

* Output Capacitor can be small to only 0.22µF
