Overview
UNISONIC TECHNOLOGIES CO.
, LTD L5107 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 TSSOP-16 * Input voltage range: 6V~45V * Feedback voltage: 0.
25V±3% * Maximum ou...
