Doesn’t post to United States See details. The pins are labeled different on the spec sheets but they are electrically the same. The reason it is running hot is due to poor DC filtering of the power supply, if the DC filter caps are not filtering properly due to high ESR and lower capacitance, the high frequency AC ripple will be riding through to the inverter circuits and modulate the high frequency switching of the inverter circuits the frequency of the SMPS and the inverter PWM are not the same, both signals will add and subtract to produce the side band frequencies, so the switching frequency will be off from the original design requirement which will cause the transformers and the switching devices to get hot.

Also this might come in handy if anyone in the future comes across this post. I could just mount it on the bottom of the board upside down. People who viewed this item also viewed. The seller hasn’t specified a postage method to United States.

I thought about using some tiny heatsinks on top of them but if i can go the SMD route and bottom mount it then i will just use the rf shield as the heatsink. Add to Watch list Watching Watch list is full. Read more about the condition. Learn more – opens in a new window or tab.

The reason i posted this in this section is because this is a very common “problem” chip on the DACM power board that is used in Multiple monitor brands. I am curious about the function of Q in the power supply.

I don’t see the problem in tying them to ground instead of the sources of the FET why do you thing this will be an issue? What’s going to happen to the FET P when this happens? Last edited by budm; at Have you started the PCB layout yet?

Last edited by Alup; at AOP Replacement well, they tried to but i guess it was not enough copper on the trace because most of the boards i have are like dark brown around the chips. Description Postage and payments. Ask a Question Want to reply to this thread or ask your own question?

The system will be controlled by an Attiny85 or by an ATMega for two channel application. I could buy a SMD to Throughhole adapter and use that. AOP Replacement But will the above chip work? Space is limited on the board and as I will use toner transfer method for the PCB the traces cannot be too thin.
