The EVL6563S-100W offers the possibility to test these functions by connecting it to the
cascaded converter via the series resistors R28, R29, R30. Regarding the PWM_STOP (pin
#9) pin that is an open collector type, if it needs a pull-up resistor, please connect it close to
the cascaded PWM for better noise immunity.
