LINEAR INTEGRATED CIRCUIT

CONSTANT CUTTENT BOOST

CONTROLLER FOR DRIVING

HIGH POWER LEDS



DESCRIPTION

The UTC L5107 is a high powered PWM boost converter

optimized for constant current applications such as driving one or

more strings of high power LEDs. The powerful drive circuitry can

deliver up to 70W to the LED system.

The output current can be set by an external resistor

connected the IADJ pin and GND. This average current can be

reduced by applying a PWM signal to the PWMD pin. The UTC

L5107 offers a dither feature to reduce EMI.

The UTC L5107 has a large input voltage range from 6V to

45V and the switching frequency can be set by an external

resistor between 100kHz and 1MHz for diffident LED systems. To

protect the device over voltage protection circuit and under

voltage lock-out circuit have been incorporated as well as thermal

shutdown circuit.



FEATURES

* Input voltage range: 6V~45V

* Feedback voltage: 0.25V±3%

* Single pin for PWM dimming

* Protection circuit:

* Maximum out power of 70W
