Auxiliary power supply

Figure 14 shows the schematic of the auxiliary power supply for the EVAL-M1-IM523 board. The circuit includes
the latest CoolSET 5 (ICE5GR4780AG) from Infineon and a flyback topology with direct output of 15 V and 6 V.

The linear voltage regulator TLE42744DV50 generates 5.0 V from a 6 V power supply VCC. The 5.0 V power
supply is used in the inverter's external overcurrent comparator circuit. Both VCC and 5.0 V are also present on
the 20-pin iMOTION™ MADK-M1 interface connector to power the circuitry on the control board.
