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
