* Built-In Open Circuit Protection * Built-In Over Voltage Protection * High Efficiency(Up to 84% at VIN=4.2V, 3 LEDs, ILED =20mA) www.DataSheet4U.com * 1.2MHz fixed swit.

Capacitor Selection: The small size of ceramic capacitors (1µF input with 1µF output ) are sufficient, X5R and X7R type.

The UTC L5101 is a fixed frequency step-up PWM DC/DC converter and designed for white LEDS driving with a constant current to provide backlight in handheld devices. The device switches at a high frequency 1.2MHz by an internal N-channel MOSFET switch.
