LED DRIVER WITH

AVERAGE-MODE CONSTANT

CURRENT CONTROL



DESCRIPTION

The UCL5108 is an average current mode control LED driver IC

operating in a constant off-time mode. UCL5108 does not produce a

peak-to-average error, and therefore greatly improves accuracy,line and

load regulation of the LED current without any need for loop

compensation or high-side current sensing. The output LED current

accuracy is ±2%. The UCL5108 can be powered from an 8.0 - 100V

supply. PWM & Linear dimming input is provided that accepts an

external control TTL compatible signal. The output current can be

programmed by an internal 250mV reference.
