CN5502 Overview
The CN5502 current regulator operates from a 4V to 32V input voltage range and delivers up to a total of 1A to one or more strings of high-brightness LEDs. The output current of the CN5502 is adjusted by using an external current-sense resistor in series with the LEDs. A dual-mode DIM pin and on-chip 130Hz PWM generator allow PWM dimming with an analog or PWM input signal.
