SL3048A
100V,3A,420KHz,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.
