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
