LM2631

Synchronous Step-Down Power Supply Controller

LM2631 Features

* include the external synchronization pin, and the PGOOD pin to indicate the state of the output voltage. Protection circuitry includes thermal shutdown, undervoltage and overvoltage shutdown protection, soft-start capability, and two levels of current limits: The first level simply limits the load c

LM2631 General Description

The LM2631 controller provides all the active functions for step-down (buck) switching converters. These dc-to-dc converters provide core CPU power in battery-operated systems. High efficiency is achieved by using synchronous rectification and pulse-skipping mode operation at light load. Inexpensive.
