SC603 General Description


The SC603 is a versatile charge pump designed for use in battery operated power supply applications. The wide input range is matched for Li-Ion battery applications. Only two tiny ceramic bucket capacitors are required, and the inductorless implementation provides a reduced-EMI solution. Low noise mode switching circuitry and constant output current allow the use of extremely small input and output capacitors.

The SC603 charge pump regulator can be used for applications that require up to 200mA of output current with a 4.5V output. The 5.0V output version provides up to 160mA of output current.

Compared to a switch mode regulator, the SC603 offers a solution with less cost, area, noise and complexity.
