4.1. DC-to-DC converter to generate VDD

The controller board has an on-board DC-to-DC step-down buck regulator that will supply power for
the entire controller board, and for development board if selected, see
to-DC regulator is supplied through the VIN connection (J1) from the 3-phase inverter board, which
is discussed in
DC-to-DC converter with internal synchronous switches that provide current for output loads up to
0.6 A.
