AN33013UA is 1-channel DC-DC Step down Regulator
integrated N-channel Power MOSFET and employs the
voltage mode switching control system.
This IC can be operated with wide input voltage range
and is build in several protection functions, so this IC can
provide high reliability power supply system.
Since it is possible to use up to 2 MHz switching
frequency and it is unnecessary to add external parts for
High Side Switch, this IC realizes downsizing of set and
reducing in the number of external parts.
Output voltage is adjustable by user.
Maximum current is 1.5 A.
High Input Voltage Power Systems such as
・Home Appliances etc.
