TOP250NY

Posted by: uoaqj4g1 on

dier sir

we have a 1000w class t power amp /and i use top250ny (+- 95 v out put dc)

i now from my experiment that in audio i dont need more then 1000/8 input power from the maims

so i conclude that TOP250YN  it ok 'and it working 'but the problem is that the curent limit sens

is so high sensetiv that it opret after sohert time of spick 'my qustin uf ut ok that i chang the resistor

12k in pin x and slove the problem

best regard

It is not clear for me what you are trying to say.

The resistor connected from X pin of the controller (TOPSwitch) to the primary return, is used to adjust  the ILIMIT of the controller. You can see in the datasheet of the TOP250 the relationship between the value of the resistor and the ILIMIT of the device.

If you have more questions, I suggest you post your schematic for me to better undersatand your issue.
