More Information

The LM27951 is a switched capacitor white-LED driver capable of driving up to four LEDs with 30 mA through each LED. Its four tightly regulated current sources ensure excellent LED current and brightness matching. LED drive current is programmed by an external sense resistor. The LM27951 operates over an input voltage range from 2.8 V to 5.5 V and requires only four low-cost ceramic capacitors.
