High Efficiency Charge Pump Converter

ON Semiconductor 

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.

Features

• Wide Battery Supply Voltage Range: 2.7 < VCC < 5.5 V

• Automatic Operating Mode 1X, 1.5X and 2X Improves Efficiency

• Dimmable Output Current

• Up to 350 mA Output Pulsed Current

• Selectable Output Voltage

• High Efficiency Up To 90%

• Supports 2.5 kV ESD, Human Body Model

• Supports 200 V Machine Model ESD

• Low 40 mA Short Circuit Current

• Pb−Free Package is Available

Applications

• High Power LED

• Back Light Display

• High Power Flash
