DESCRIPTION
The SL3018 is a monolithic
stepdown switch mode controller with a programmable output current
limit.It achieves continuous out put current over a wide input
supply range with excellent load and line
regulation.
The maximum output current
can be programmed by sensing current through an accurate input
sense resistor.
It can out put constant
voltage. Internal thermal shutdown, cycle-by-cycle currentlimit
protect ion.
The SL3018 requires a minimum
number of readily available standThe chip is available in 8-pin
SOIC8 packages.
