General Description
NMSD200B01 is best suited for switching voltage regulator
and power management applications. It improves efficiency
and reliability of DC-DC converters 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 parastic losses. The component devices
can be used as a part of a circuit or as a stand alone discrete
device.
