ON Semiconductor CS51033 handbook
Update: 30 September, 2023
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 PFET duty cycle to approximately 1/30 of its normal cycle during short circuit conditions. The CS51033 is available in an 8-Lead SO package.
