General Description

This demonstration board utilizes the
AP3041 high voltage low-side N-channel
MOSFET controller ideal for boost
regulators. It contains all the features
needed to implement single-ended primary
topology DC/DC converters. The input
voltage of AP3041 ranges from 5V to 27V.
Its operation frequency is adjustable from
100kHz to 1MHz.

The AP3041 has UVLO (Under Voltage Lock
Out) circuit. It uses two external resistors to
set the UVLO voltage. The AP3041 also has
an over output voltage protection to limit
the output voltage. The OVP voltage can be
set through external resistors. If the output
voltage is higher than the OVP high
threshold point, it will disable the driver
and the system is latched up. The output
short circuit protection as well as LED low
side short to ground detection function can
be applied in system.

The AP3041 has other protection functions,
such as LED short protection, LED high side
short to ground protection, diode short
protection, over current protection, over
temperature protection and so on.

Applications

• LED Lighting

• LED TV

• LCD Display Modules
