... 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 ...

... EN/PWM = High → the chip is activated and the load is connected to the regulated output current. The NCP5603 can operate either in a continuous mode (EN/PWM = High), or can be controlled by a PWM pulse applied to EN/PWM to dim the output light. When EN/PWM is Low, the external load is disconnected from the converter, providing a very low standby current. The pull down built− ...
