Typical Application Circuit
The SC613 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 1uF ceramic
bucket capacitors are required, and the inductorless implementa-
tion provides a reduced-EMI solution. Low noise mode switching
circuitry and constant output current allow the use of 1uF input
and output capacitors.
The SC613 charge pump regulator can be used for applications
that require up to 140mA of output current with a 4.5V output.
The 5.0V output version provides up to 100mA of output current.
The small package size, low component count and lower overall
system cost coupled with its low noise make the SC613 a supe-
rior solution compared to switch mode regulator designs.
