Additional preview pages of the LM20123 datasheet.

The LM20123 is a full featured 1.5 MHz synchronous buck regulator capable of delivering up to 3A 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 LM20123 is designed to work well in multi-rail power supply arc.
