UcD like topology amp.

[Whortless]

hello Whortless
good job1 i like it)
but same question to you..
do U synchronized all your drivers IRS???
how u do it, if yes (sorry for my english)

Hi Kvazi13,
I am so sorry to answer very late. I can do this but i did not actually. There is a way to synch. them from input via an external osc. and my all amps has synch inputs which are disconnected now. Instead i used 47nf caps between the outputs for each R+L channels to synch. However, it does not look very necessary. All the amps running at nearly same frequency 387-390kHz without synching. I just finished the auxiliary PS for input opamps (OPA1632)+ comparator (LM311) and output relay protection boards which are ordered from seed studio.

I will add some photos soon.

Best wishes,
FH

Can anybody post the schematic and pcb for Bender's amp - none of the links work anymore and since he was willing to share I don't see any harm - or PM me if not to be posted ?

Hello
greetings can any one advice me on how to design pcb for this schematic
single sided or double sided
warm regards

Req: CakeAmp v3 Schematic!

Is this what you're looking for?

Thanks!
Was v3 ever published? If yes, is there any circuit change in v3 or was it just with added protection for OV and UV?

Thanks in advance!!

Hi Andrew
Looks like an old design. Why go with IR2110, needing level shifter on the input and over current protection seperately ... go with a IRS20957 .... maybe even the cake amp in 3 posts earlier ...

But to your question ... yes go for 2 sided and smd components

I find this design so much better than the 25W to 1200W design.
This has less component count, a much better driver with OC protection and dead-time setting.

I wonder why the other got so much attention.

This one would be good to try as both half bridge and full bridge.

Highly agree

No need to, it because of

1200W

This design is bad, although they put a dedicated circuit to eliminate the offset, and balanced input, does not stop making noise, is a random design ........
