BOOST CONTROLLER AP3039
Data Sheet

BCD Semiconductor Manufacturing LimitedJun. 2010 Rev. 1. 6
General Description
AP3039 is a current mode high voltage low-side N-
channel MOSFET controller which is ideal for boost
regulators. It contains all the features needed to imple-
ment single ended primary topology DC/DC
converters.
The input voltage range of AP3039 is from 5V to 27V.
Its operation frequency is adjustable from 150kHz to
1MHz.
The AP3039 has UVLO (Under Voltage Lock Out)
circuit. It uses two external resistors to set the UVLO
voltage. The AP3039 also has an over output voltage
protection to limit the output voltage. The OVP volt-
age can be set through external resistors. If the output
voltage is higher than the OVP high threshold point, it
will disable the driver, when the output voltage drops
to the OVP low threshold point, it will enable the
driver. It also features a soft start to reduce the inrush
current when power on, the soft start time can be set
through an external capacitor.
The AP3039 is available in QFN-3x3-16 and SOIC-14
packages.
