LM22678-Q1 - Step-Down Voltage Regulator

Download the LM22678-Q1 datasheet PDF. This datasheet also covers the LM22678 variant, as both devices belong to the same step-down voltage regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM22678 switching regulator provides all of the functions necessary to implement an efficient highvoltage step-down (buck) regulator using a minimum of external components.

This easy-to-use regulator incorporates a 42-V N-channel MOSFET switch that can provide up to 5 A of load current.
