CONSONANCE
High-Voltage, Linear High-Brightness LED Driver IC
with Analog and PWM Dimming Control
CN5502
General Description:
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.
The analog control signal at dimming input DIM allows for a theater-dimming effect to be implemented.
The CN5502 is well suited for applications requiring high-voltage input and is able to withs...
