CS51031 Datasheet Fast Pfet Buck Controller

Manufacturer: Cherry Semiconductor Corporation

Overview: CS51031 CS51031 Fast PFET Buck Controller Does Not Require Compensation.

General Description

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, 1.0A 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.
