DESCRIPTION
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.
APPLICATIONS
High Input Voltage Power Systems such as
Car-Audio system
Car-Navigation system
OA Equipment
Home Appliances etc.

Notes) Do not apply external currents and voltages to any pin not specifically mentioned.
This product may sustain permanent damage if subjected to conditions higher than the above stated absolute maximum rating.
This rating is the maximum rating and device operating at this range is not guaranteeable as it is higher than our stated
recommended operating range. When subjected under the absolute maximum rating for a long time, the reliability of the product
may be affected.
Vcc is voltage for VCC, PVCC1 and PVCC2. VCC = PVCC1 = PVCC2.
