General Description
?
NMSD200B01 is best suited for switching voltage
regulator and power management applications. It
improves efficiency and reliability of DC-DC controllers
used in Voltage Regulator Modules (VRM) and can
support continuous maximum current of 200mA. It
features an ESD protected discrete N-MOSFET with low
on-resistance and a discrete Schottky diode with low

forward drop. It reduces component count, consumes
less space and minimizes parasitic losses. The
component devices can be used as a part of a circuit or
as a stand alone discrete device.
