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.  
The UTC L5107 is available in the HTSSOP 16-pin TSSOP  
package.  
FEATURES  
* Input voltage range: 6V~45V  
* Feedback voltage: 0.25V±3%  
* Maximum out power of 70W  
* Programmable switching frequency and LED drive current  
* Ultra low EMI via dithering on the UTC L5107  
* Single pin for PWM dimming  
* Protection circuit:  
Over voltage protection circuit  
Over temperature protection circuit  
Under-voltage Lock-out circuit  
* Accurate over the -40~125°C temperature range
