Data Sheet
Boost Controller for WLED Driver in Medium-sized LCD Panel AP3041
General Description
The AP3041 is a current mode high voltage low-side
channel MOSFET controller, which is 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.
The AP3041 is available in SOIC-16 package.
