SP6137HV - Dual Supply Synchronous Buck Controller

General Description

The SP6137HV is a synchronous step-down switching regulator controller optimized for high efficiency.

The part is designed to be especially attractive for dual supply, 12V step down with 5V used to power the controller.

This lower VCC voltage minimizes power dissipation in the part.
