Description	Synchronous Buck Regulator
Datasheet	LM20124_NationalSemiconductor.pdf

The LM20124 is a full featured 1 MHz synchronous buck regulator capable of delivering up to 4A 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 LM20124 is designed to work well in multi-rail power supply arc.
