General Description

The LM20144 is a full featured adjustable frequency synchronous buck regulator capable of delivering up to 4A 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.
