QUICK START GUIDE
The AP63300-EVM
has a simple layout and allows access to the appropriate signals through test points.
To evaluate the performance of the AP63300, follow the procedure below:
1. For evaluation board configured at V
OUT
=5V, connect a power supply to the input terminals V
IN
and
GND. Set V
IN
to 12V.
2. Connect the positive terminal of the electronic load to V
OUT
and negative terminal to GND.
3. For Enable, place a jumper
to “H” position to enable IC. Jump to “L” position to disable IC.
4. The evaluation board should now power up with a 5V output voltage.
5. Check for the proper output voltage of 5V (±1%) at the output terminals V
OUT
and GND. Measurement
can also be done with a multimeter with the positive and negative leads between V
OUT
and GND.
6. Set the load to 3A through the electronic load. Check for the stable operation of the SW signal on the
oscilloscope. Measure the switching frequency.
