BOOST CONTROLLER
General Description
Features
Preliminary Datasheet
AP3039A
The AP3039A 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 AP3039A is from 5V to
27V. Its operation frequency is adjustable from
150kHz to 1MHz.
The AP3039A has UVLO (Under Voltage Lock Out)
circuit. It uses two external resistors to set the UVLO
voltage. The AP3039A 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.
· Input Voltage Range 5V to 27V
