Hello!
I am using a TPS54140 to supply a 3,3V output. The EN-pin is designed for an input voltage of 7,4 (EN > 1,25 V) but won't turn on when EN-pin is less than 1,5 V (8,9 V input). For the voltage divider I use a 392k and a 80,6k resistor. However the device turns on when the input voltage is above 8,8V and the EN-pin is above 1,5V. What could be the cause of this problem?
