LM20143-Q - Texas Instruments

LM20143-Q Adjustable Frequency Synchronous Buck Regulator

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 compensated to be stable with virtually any type of output capacitor. For most cases, compensating the device only requires two external components, providing maxi.
