NCP5608
Multiple LED Charge Pump
Driver
The NCP5608 is a high efficiency boost converter operating in
current loop, based on a charge pump multi mode, to drive White
LED. The current mode regulation allows a uniform and
programmable brightness of the LEDs. The chip has been optimized
for small ceramic capacitors, capable to supply up to 2.0 W output
power.
