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.
