LM20146 Overview
The LM20146 is a full featured adjustable frequency synchronous buck regulator capable of delivering up to 6A of continuous output current. The current mode control loop can be pensated to be stable with virtually any type of output capacitor. For most cases, pensating the device only requires two external ponents, providing maximum flexibility and ease of use.
