Fast PFET Buck Controller

Does Not Require Compensation

Features

Description

The CS51031 is a switching con-

troller for use in DC-DC converters. allows the use of small inductors

The high frequency oscillator

■ 1A Totem Pole Output

Driver

It can be used in the buck topology

with a minimum number of exter-

nal components. The CS51031 con-

sists of a V_CCmonitor for control-

ling the state of the device, 1.0A

power driver for controlling the

gate of a discrete P-channel transis-

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

■ High Speed Oscillator

(700kHz max)

■ No Stability

The CS51031 is available in 8L SO

grammable soft start, precision ref-

and 8L PDIP plastic packages.

■ 2% Precision Reference
