Auxiliary power supply

Figure 32 depicts the schematic of the auxiliary power supply for the EVAL-M3-IM564 board. The circuit includes
an ICE5QR4770AG that is used to generate 15 V and 6V through QR flyback topology from the DC bus.
Figure 32 Power supply section of the EVAL-M3-IM564 Evaluation board
The linear voltage regulator IFX1117ME V33 generates 3.3 V from 6V power supply. The 3.3 V power supply is
used in the PFC overcurrent comparator circuit and overtemperature hardware protection circuit. Both 15V and
3.3 V are also present on the 30 pins iMOTION™ MADK-M3 interface connector J3 to power circuitry on the
control board.
