Patent number: 9578701Abstract: This disclosure is directed to techniques for efficiently driving multiple light emitting diode (LED) strings from a single regulated source. The techniques of this disclosure may utilize a switched capacitor DC-to-DC converter between the regulated source and the LED string.
