SC600AIMSTR

mAhXLife LED Driver with 5.0V, 4.5V, or 4.0V Output TM SC600 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. 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. 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. mAhXLifeTM LED drivers replace switched mode power supplies and provide comparable efficiency with less cost, area, noise, and complexity. Features Small size - MLPD 10 lead 3x3mm or MSOP-10 package allows for a complete solution in .05 sq. in. Peak efficiency over 90% (extends battery life) Four component versions available 60mA versions available in 5.0V and 4.5V output 120mA versions available in 4.5V and 4.0V output Short-circuit and over-temperature protection Soft-start function Shutdown current
