Datasheet Summary
UNISONIC TECHNOLOGIES CO., LTD
LINEAR INTEGRATED CIRCUIT
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 allow the use of tiny external ponents. The output capacitor can be as small as 0.22μF; saving space and cost pare with alternative other solutions. The low 95mV feedback voltage minimizes power loss in the current setting resistor can have better efficiency.
