Just one last question, what purpose do J16, J17 and J18 serve?

These allow you to use an external inductor (J17 - external inductor - J18) or the inductor included on the board (J17 - J16).

Thanks Kyle. Sorry I had another question. Can you please help me understand why these nets are not connected? specifically pins 1, 16. I see the same in the PCB doc when I update teh changes from the schematic to the PCB doc.

Also I am not seeing the source nets for 5V_H and 5V_L. Is there something I am missing?

Hey Gautham,

These pins are no connect pins, as specified in the data sheet. They are used as anchor pins to mechanically connect the QFN package to the PCB. They are meant for mechanical connection, not electrical connection.

The 5V_L/5V_H is produced from the LDO5V pin on the device. The device creates this 5V rail to power digital isolator, current sensors, or other peripherals.

Best,

Kyle Wolf
