mAhXLife
TM
LED Driver with
5.0V, 4.5V, or 4.0V Output
POWER MANAGEMENT
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.
mAhxLife
TM
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 implemen-
tation provides a reduced-EMI solution. Patented low
noise mode switching circuitry and constant output cur-
rent allow the use of extremely small input and output
capacitors.
The SC600 charge pump can be used for applications
that require up to 120mA of output current with a 4.0V
or 4.5V output. The 5.0V output version provides up to
60mA of output current.
mAhXLife
TM
LED drivers replace switched mode power
supplies and provide comparable efficiency with less cost,
area, noise, and complexity.
