森利威爾 SL3048A

100V,3A,4 20KHz,Switching Current Limit Step-Down Converter

DESCRIPTION

The SL3048A is a monolithic IC designed for a

step-down DC/DC converter with low EMI

signature, and own the ability of driving a peak

3A continuous current, with excellent load and

line regulation. The SL3048A also can run at

98% duty cycle for low dropout operation, and

Internal soft-start results in small inrush current

extending battery life in portable systems. As a

protection function, it has cycle by cycle peak

current limit function, short protection function,

thermal shutdown function and UVLO. The

device is available in a 8-pin small profile

ESOP8 package.
