LM22678 Overview
The LM22678 switching regulator provides all of the functions necessary to implement an efficient highvoltage step-down (buck) regulator using a minimum of external ponents. This easy-to-use regulator incorporates a 42-V N-channel MOSFET switch that can provide up to 5 A of load current. Excellent line and load regulation along with high efficiency VIN VIN FB (> 90%) are featured.
