Datasheet
6 V to 28 V, 1.2 A 1ch
Step-Down Switching Regulator
Integrated Power MOSFET
BD9E151ANUX
General Description
Key Specifications
BD9E151ANUX is diode-rectification buck converter of
high input voltage 28 V with integrated Power MOSFET.
Because of diode-rectification, a pulse skips in light load
automatically and it maintains high efficiency. In addition,
it is available for battery powered application because
supply current is small with 0 uA at shutdown. It can easily
make a small power supply with the external parts of the
wide range, because the use of ceramic capacitor is
possible, and because it has high speed road response by
current mode control and has the external setting phase
compensation.
