Hi Irfan, based on your describtion our expert can't figure out what happen in your application. Please offer the schematic and capture the abnormal waveform then we can help you to analysisi what happened.
Hi Robin, please help in this case and offer your requirment to Irfan.
Hi Irfan,
The control of this device doesn't support extremely fast loop response, which means shunt FET dimming is not a good idea.

Hi,
We are use Al8807 driver IC. it is support 4 external shunt midget support with linear current dimming. Now it is obsolete that's why we have select tps92513.
Attached some waveform which helps to you.
