A81407 Overview
The A81407 is ideal for both automotive and industrial applications, where high temperature operation, a high level of integration, and robust solutions are required. The IC integrates a buck or buck/boost pre-regulator, four LDOs, and four floating gate drivers. The pre-regulator uses a buck or buck/boost topology to efficiently convert input voltages into a tightly regulated intermediate voltage.
