SC600EVB規(guī)格書詳情
Description
The SC600 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. mAhxLifeTM LED Drivers feature a fractional charge pump implementation with efficiency comparable to a switching regulator without costly inductors. Only two tiny ceramic capacitors are required, and the inductorless implementation provides a reduced-EMI solution. Patented low noise mode switching circuitry and constant output current allow the use of extremely small input and output capacitors.
