LM2631 controller equivalent, synchronous step-down power supply controller.
include the external synchronization pin, and the PGOOD pin to indicate the state of the output voltage. Protection circuitry includes thermal shutdown, undervoltage and .
bringing the FPWM pin high can force the device to operate in constant frequency mode. Other features include the exter.
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-.
