NCP5603
High Efficiency Charge Pump
Converter
The NCP5603 is an integrated circuit dedicated to the medium
power White LED applications. The power conversion is achieved by
means of a charge pump structure, using two external ceramic
capacitors, making the system extremely tiny. The device supplies a
constant voltage to the load from a low battery voltage source. It is
particularly suited for the High Efficiency LED used in low cost, low
power applications, with high extended battery life.
