CS51031YD8 [Onsemi]

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. Programmable Soft−Start reduces current surges at startup. The short circuit protection timer significantly reduces the duty cycle during short circuit conditions.
