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.
