We have the MC33879 in our Design. See Attachment. But we noticed that the Output Voltag is way below our Input Voltage.
A Small load of a single relais with ~20 mA drops the Voltag to 19V.
The Power supply is ok, the Voltage stays in a range of 23.90 to 24.20 V on the D-inputs of the MC33879. But the S-Outputs of the MC33879 is with 19.xx Volt quite low.
Where are those 4 to 5 Volts lost?
