General Description

The BD9328EFJ is a synchronous step-down switching regulator with built-in two low-resistance N-Channel MOSFETs.

This IC can supply continuous output current of 2A over a wide input range, and provides not only fast transient response, but also easy phase compensation because of current mode control.
