Nov 30, 18, 9, Here’s two more improvements he mentions, with a final one being a 4 output option: Be very weary with NTE parts, they are known to be remarked devices that does not match the original parts spec what so ever. Hello, Have a good look at the transformers connections.

In this teardown, we will datashwet inside a TP link powerline adaptor to see what makes this thing tick!

May 5, 6. I think I got the wrong form factor for the mica, but I bet I can make it work TP Link Powerline Adapter With powerline adapters becoming more popular, it’s about time one of these was taken apart!

I assume the book also explains some of the circuits? Phasor Member Dec 19, This puts you in the position of learning heat flow. May 6, 7. For the “transistor-y section”: Especially that transistor chapter.

Yes, my password is: I made some remarks in the schematic you posted: This design seems good for learning though. Replacement Transformer Started by ncag Today at 7: Meantime,If someone knows an equivalent please tell me OR give me any links.


Looking for a datasheet and equivalent. To compensate for this the raw input supply dataasheet high so that Q3 and Q4 can draw enough current through R1 and R2 to supply the pass transistor base drive and and also their datasueet needs.

Thanks so much for your time. Microcontroller and possible compatible replacements. Forums New posts Search forums. Quote of the day. TheOne New Member Dec 20, May 4, 1. You May Also Like: Resistance to heat flow is called, “theta” and this resistance is always defined as between two places.

Ravi Colombo Sri lanka. Do you already have an datashert May 4, 2.

Datasheets, Manuals or Parts. It is nice to hear from you again as I was not available in this forum for a long time. May 7, It goes into current limit mode at about 1. Don’t forget the HUGE heatsinks and fans. It’s a character flaw, or the fact that I’m where the town where the phrase “New York Second” originated You’re going to be using one or two chunks of aluminum about the size of your fist.

To participate you need to register. Theta junction to case of the transistortheta case datasheef heat sink, theta heat sink to air, all add together.

If you post a schematic diagram that will help a lot. Automated print removal has been on the edge of the consumer market for a long time; will the VMPro finally be the printer to bring this feature to makers everywhere?


In the end, the question of datsheet using the chassis for heat dissipation is wise or not may be overshadowed by my obvious ignorance and the fact that I’m sure that there are better designs for a power supply.

You must log in or register to reply here.

The unit will provide two independently adjustable outputs, positive and negative of about 4V to 15V each, as well as a ground. Yeah, I’ll be attaching it to the aluminum chassis for heatsinking For a better 2c3281, please enable JavaScript in your browser before proceeding. I wonder if the mods he has later in the book deal with that. Thread starter Ravi Start date Dec 19, Maybe I need to look and double check I understand the front end of that circuit.

The datasheet of the transistors will tell you dataxheet of this, like maximum temperature allowed and the heat flow resistance of the transistor. The gain of the pass transistors is low which is why 2cs3281 are recommended as an improvement and the supply differential amp gain is also low Which is why he recommended an op amp.

Hello Phasor, Thanks very much Phasor.
