LM27952 - white-LED Driver
The LM27952 is a switched capacitor white-LED driver capable of driving up to 4 LEDs with 30mA through each LED.
Its 4 tightly regulated current sinks ensure excellent LED current and brightness matching.
LED drive current is programmed by an external sense resistor.
The LM27952 operates over an inp
