HI TI Experts
In TIDA-0038,the PWR050A written that the VIN_MON 400V=1.93V,but in the PWR050A SCH ,that written 400V=1.5V,Please help me to make sure which one is right? How to calculate the VIN MON GAIN? Thank you !

Hello,
Here is the aux transformer turns ratio. The transformer part number is GA358. Pri:Sense = 1:0.079. Another voltage divider is from: R16 and R14. N = R14/(R14 +R16). Then you can calculate the sensed voltage,
