Fast PCh FET
Buck Controller
The CS51031 is a switching controller for use in DCDC
converters. It can be used in the buck topology with a minimum
number of external components. The CS51031 consists of a V
CC
monitor for controlling the state of the device, 1.0 A power driver for
controlling the gate of a discrete PChannel transistor, fixed frequency
oscillator, short circuit protection timer, programmable SoftStart,
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 SoftStart reduces current surges at startup. The short
circuit protection timer significantly reduces the duty cycle to
approximately 1/30 of its cycle during short circuit conditions.
