DC915A, Demonstration Board using LT3466-1 step-up converter, high efficiency white LED driver

DC915A, Demonstration Board using LT3466-1 high efficiency white LED driver and step-up converter. There is one LED driver output for 8 WLEDs and 2 normal outputs for LCD. VO1 drives 8 LEDs in series with 15mA LED current and VO2/VO3 can delivery +/- 15V at 10mA current. If the charge-pump circuitry (C4, C5 and D1), which generates VO3, is removed, VO2 can deliver over 35mA of current. The input voltage range is 3V to 14V, which can go as low as 2.7V with slightly reduced output current
