AP3039
BOOST CONTROLLER
Description
Pin Assignments
The 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 implement 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
voltage 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.

Typical Applications Circuit (Cont.) (Note 1, 2 and 3)
Note 1:
The output voltage is decided by R5, R6 and the internal 0.5V reference. The output voltage accuracy is determined by the accuracy of R5 and R6, for which
the precise resistors are preferred.
VOUT= 0.5V *
R6
Note 2:
R5 R6
In this application, the LED current is controlled by the feedback resistor R5. LEDs current accuracy is determined by regulator’s feedback threshold
accuracy and is independent of the LEDs forward voltage variation. So the precise resistors are the better choices. The resistance of R5 is in inverse proportion to the
LED current since the feedback reference is fixed at 0.5V. The relation of R5 and the LED current can be expressed as below:
R5=
0.5V
I LED
Note 3:
The summation of LED current is determined by R5 and internal 0.5V reference same as the illustration in Figure 22.
More detailed application information please refer to application note.
