Description	Synchronous Buck Regulator
Datasheet	LM20125_NationalSemiconductor.pdf

The LM20125 is a full featured 500 kHz synchronous buck regulator capable of delivering up to 5A of continuous output current.

internal over voltage protection (OVP) and over current protection (OCP) circuits for increased system reliability. A precision enable pin and integrated UVLO allows the turn-on of the device to be tightly controlled and sequenced. Start-up inrush currents are limited by both an internally fixed and externally adjustable Soft-Start circuit. Fault detection and supply sequencing is possible with the integrated power good circuit. The LM20125 is designed to work well in multi-rail power supply arc.
