On Semiconductor has introduced a white LED driver designed to drive high brightness LEDs in torch or flash applications.

The NCP5603 provides power conversion by means of a charge pump structure, using two external ceramic capacitors, and is designed to remove the need for a bulky inductor to implement the power conversion.

Offered in a DFN-10 package measuring 3x3x0.9mm, the LED driver supplies a constant voltage to the load from battery voltage ranges between 2.7V to 5.5V.

Because the device allows a high output current pulse of up to 350mA, it is suitable to drive a high brightness 1W power LED.

The device also features a PWM/EN input, suitable for dimming requirements.
