sir,
the blowout happens at all voltages from 85Vac to 265Vac,but few of the devices are working for the past 6 months,out of five smps two of them work and three blows off with the 10E resistor.
hi,
tny276 use current limit state machine to decide whether or not to implement a switch a switch cycle. Could you give me some more information about how current limit state machine works,whether the value of current limit is discret or continus,and the highest/reduced value.thank you!
What is the differences between the following 2 IC's the TOP205Y and TOP250YN please?
Is your question is whats the difference between TOP250 Y and TOP250YN ?
Would you please give us more information such as the input voltage and output voltage /current when this happened? Does this happen only at high line voltage at all voltages from 85Vac to 265Vac?
