BD9328EFJ-LB
General Description
This is the product guarantees long time support in
Industrial market.
The BD9328EFJ-LB 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.
