thanks
i dont have more pin in my micro to creat thermal with micro
if i want use micro for that i must change my micro ic with Atmega 1280 or some thing like that to have enoufe pin to do that and even i need to use interupt for sensor
it make my micro PCB messy
thanks for your helping

So, did anyone build the amplifier on the first page (or an improved version of it) ?
If so, how does it measure and how does it sound ?

load testing on 400 Watts

Did you use the core I recommended?
this nucleus has to calculate the primary

Hi friends
sir manoj
i am wating for your reaply and for converter
thanks very much

 

[manojtm]

manojtm ,what chip do you use for dts/ac3 digital input?To my knowledge there is none available for public due to copyright law.

Hi CPX,

good day man we need your valuable comments i am very happy you are again join here

not one single IC complete circuit with SPDIF input

MANOJ

thanks for your reaply but i dont know hove can i use that
i mean hove can control amp with this thermal switch
were i must conect it?

Hi Hadi,

connect across 100n capacitor in power AUD600 board.near by 12V bias connection(center pin and -ve pin)

Hi Hadi,
You can use this. this is not my circuit

thanks Friend
i creat this befor with IRFZ44N mosfet
it wath work good
this is kenwood KAV-716 smps
this smps can handel 300 watt if drive mosfets good
we need more power
how can i drive more mosfet with this?
how can i increse this smps ferecuence?

Hi
i need mosfet driver for drive 5 + 5 IRFZ44N for this smps
any sugetion?

 

[Hadighorbani]

is TC4420 enoufe for drive 5 IRFZ44N ?

 

[fra]

For 4 or even 5 is enough 500mA. they can directly drive the SG3525 on 50khz

thanks fra

Hi Hadi,

Use IRF3205 x 2 with 47 Ohm gate resistor freq=80KHz or 100KHz. Primary turns 3+3

Hi my dear friend
it is not posible to handel 110A in TO220 case.
you mean i must use 4 IRF3205 ?
can this handel + - 30VDC 20A ?
thanks for your reply

If someone wanted to build this amp, one 1N4148 diode has wrong direction.

hi fra, what type of toroidal core can i used on this design? it may handle a large amount of current is it a low or high permeability type?any idea and how about the outside & internal diameter, thickness of this core that your going to used?is it available in the market?thank's

I use a t106-2 core.
You might need a slightly bigger core for your current needs.
the t106 is 1.06 inches diameter and the -2 is the core type.
