TOP 250Y failure
We are purchased TOP250Y IC for the use of Adapter making,still some batches ICs continuously failed from the field.we are using the same design in the TOP250 datasheet circuit.Please help to findout the actual problem of that ICs.
input voltage :150 to 240 Vac
output voltage : 12v DC
Out put Current : 10A max
Adapter used to : Analyzer machine, resistive load device,
one stepper motor used ( Current below 0.600A)
One coil heater ( Used max.6A at 4 second 'ON')
