LM20123 Datasheet Synchronous Buck Regulator

Manufacturer: Texas Instruments

Overview: LM20123 www.ti.com SNVS524E – OCTOBER 2007 – REVISED MARCH 2013 LM20123/LM20123Q 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.
