1ch Step-Down Switching Regulator
BD9E151NUX
General Description
The BD9E151NUX is a 28V, 1.2A diode-rectification
buck converter that integrated internal high-side 30V
Power MOSFET. To increase efficiency at light loads, a
pulse skipping is automatically activated. Furthermore,
the 0uA shutdown supply current allows the device to be
used in battery powered application. Current mode
control with internal slope compensation simplifies the
external component count while allowing the use of
ceramic output capacitors.
