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 SC613 is a versatile, low-noise charge pump designed for portable power supply applications such as cellular phones and LED flashlights. It features an inductorless implementation to reduce EMI and requires only two 1uF ceramic bucket capacitors. The device supports input voltages from 2.5V to 6.5V and provides up to 140mA at a 4.5V output or 100mA at a 5.0V output.
| Input Supply Voltage | 2.5V to 6.5V |
