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 implementation 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 superior solution compared to switch mode regulator designs.
The Semtech SC613 is an inductorless charge pump designed for battery-operated power supply applications, particularly those using Li-Ion batteries. It offers a wide input range from 2.5V to 6.5V and provides up to 140mA of output current at 4.5V or 100mA at 5.0V.
