LM20143-Q Overview
The LM20143 devices are full featured PowerWise™ adjustable frequency synchronous buck regulators capable of delivering up to 3 A 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.
