LM20123 - Texas Instruments

LM20123 Synchronous Buck Regulator

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. .
