L5100 - UTC

L5100 WHITE LED STEP-UP CONVERTER

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 allow the use of tiny external components. The output capacitor can be as small as 0.22μF; saving space and cost compare with alternative other .
