LED Driver

4 posts / 0 new

Hello All,

 

I am facing problem in my isolated led driver.

After burning for 2-3 hrs, led drivers are not working.

If I checked low cut off voltage of driver it is working fine, but it is not recovering at 240V too.

Please help me.

What LED driver are you using?

It could be overtemperature protection (OTP). Check the device temperature. If it's OTP, it usually recovers once the temperature cools down.

It may caused by high temperature, you can measure the VCC if it is over the range your IC spec writed.
