Description
CS51031
The CS51031 is a switching con-
troller for use in DC-DC converters.
It can be used in the buck topology
with a minimum number of exter-
nal components. The CS51031 con-
sists of a V
CC
monitor for control-
ling the state of the device, 1.0A
power driver for controlling the
gate of a discrete P-channel transis-
tor, fixed frequency oscillator, short
circuit protection timer, pro-
grammable soft start, precision ref-
erence, fast output voltage monitor-
ing comparator, and output stage
driver logic with latch.
The high frequency oscillator
allows the use of small inductors
and output capacitors, minimizing
PC board area and systems cost.
The programmable soft start
reduces current surges at start up.
The short circuit protection timer
significantly reduces the duty cycle
to approximately 1/30 of its cycle
during short circuit conditions.
The CS51031 is available in 8L SO
and 8L PDIP plastic packages.
