CS51033 CS51033 Fast PFET Buck Controller Does Not Require Compensation Description 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 1.0A power driver for controlling the gate of a discrete Pchannel 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.
