POWER MANAGEMENT
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 con-
stant output current allow the use of extremely small
input and output capacitors.

Typical Application Circuit
The SC603
charge pump regulator can be used for ap-
plications 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.
