LM20123 Datasheet Synchronous Buck Regulator

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM20123 3A, 1.5MHz PowerWise® Synchronous Buck Regulator www.DataSheet4U.com January 16, 2008 LM20123 3A, 1.

General Description

The LM20123 is a full featured 1.5 MHz synchronous buck regulator capable of delivering up to 3A of continuous output current.

The current mode control loop can be compensated to be stable with virtually any type of output capacitor.

For most cases, compensating the device only requires two external components, providing maximum flexibility and ease of use.

Key Features

  • 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.
