Switch-Mode High-Brightness LED Driver
CN5610
General Description:
The CN5610 is a PFM high efficiency LED driver control IC. It allows efficient operation of high brightness LED from input voltage ranging from 3V to 450V. The CN5610 controls an external N channel MOSFET or NPN transistor at the frequency up to 300KHz. The LED string is driven at constant current rather than constant voltage, thus providing constant light output and enhanced reliability. The output current can be programmed from 30mA to 1.2A with an external resistor. The other features include soft start circuit, inductor current limit circuit, etc. The CN5610 is available in a 8-pin SOP package.
