NCP5603: White LED Driver, High Efficiency, Charge Pump Converter

The NCP5603 is an integrated circuit dedicated to the medium power White LEDapplications. 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 < 5.5V
  • Automatic Operating Mode 1X, 1.5X and 2X improves Efficiency
  • Dimmable Output Current
