CS51033

Fast P−Ch FET Buck

Controller

The CS51033 is a switching controller for use in DC−DC

converters. It can be used in the buck topology with a minimum

number of external components. The CS51033 consists of a 1.0 A

power driver for controlling the gate of a discrete P−Channel

transistor, fixed frequency oscillator, short circuit protection timer,

programmable Soft−Start, precision reference, fast output voltage

monitoring 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 P−Ch FET duty cycle

to approximately 1/30 of its normal cycle during short circuit

conditions.
