DESCRIPTION

AN33014UA 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 1 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.

For USB applications, this IC can controlled USB

supplied voltage level with external resistor for USB load

current monitor (Current Feedback Function), and it can

provide suitable power supply system for external USB

with no voltage drop due to USB cable loss.

Maximum current is 1.5 A.

APPLICATIONS

High Input Voltage Power Systems for USB such as

?Car-Audio system

?Car-Navigation system

?OA Equipment

?Home Appliances etc
