CS51031 Fast P−Ch FET Buck Controller
The CS51031 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 CS51031 consists of a VCC monitor for controlling the state of the device, 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.
