SGM37603 Description
The SGM37603 is an ultra-pact, highly efficient, triple-string white-LED driver designed for LCD display backlighting. The device operates over the 3V to 24V input voltage, it can power up to 8 series LEDs at up to 25mA per string. An adaptive current regulation method allows for different LED voltages in each string while maintaining current regulation.
