I learn a lot, specially about grounding.

Since the inductor will be carrying the full output current lm3886gf the amplifier, the wire should be heavy gauge. Use low ESR bulk storage caps and minimize inductance lengths. Truly fantastic stuff you got here! George on October 3, at 1: Though I datashret no expertise in Physics, was able to understand the technical things in this article.

YNM on August 23, at Commonly available through Moser and DigiKey. I really enjoyed reading this awesome guide!

Thank you for sharing this documented design guide for LM But I think three wire transformer output should also do just fine.


If I may offer my observations, which are purely subjective though based and no doubt influenced by research.

I ordered exactly the chassis and heatsink as specified and there is no way that the heatsink will fit in that chassis. What could be wrong?

This is where you find datqsheet flow holes across the entire top and bottom of enclosure. Audio signals are relatively low frequency, so they will flow through the inductor uninhibited.

Depending on the rectifier and diodes used, this should be anywhere from 1. Lm3886hf on February 7, at I can use it, no? From then on, I have been trying to improve its performance by making modifications. Congratulations for the excellent post!

Brad on November 15, at 5: Mustafa Kamal on November 17, at Dr Dorkmeister on May 21, at I take may hat off to you Robert. Howeveris it possible to go directly to EDA with info you posted for the amplifier board? Cc before or after Cin? Robert Thank you very much for the reply. Although your question is a year old, I will answer it with my assumptions so far after searching online with the same questions in mind. If a high current fault occurs, the fault current can flow through the diode bridge to earth.

This allows for a smaller heat sink for the required dissipation thus saving a considerable amount of space and cost. Your LM article is fantastic. At the end I wire up the amp so km3886tf can hear what it sounds like:.
