BD9328EFJ

Datasheet 4.2V to 18V, 2A 1ch Synchronous Buck Converter with Integrated FET BD9328EFJ 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.
