UCD 25 watts to 1200 watts using 2 mosfets

[stewin]

hi manoj i have managed to configure cd4049 . now the amp is working o.k .

your amp has great clarity in mids comparing to irs series amps. congratulations.

about the output inductor it is the same case as irs amps . i started with 64turns etd 42 but outputs were hot . so i switched to 22turns etd42 they became cool . my output voltage is +/- 48vlts; outputs are irfp250n, gate resistor 39ohms .
>>>the 3.3kohms 3watts resistors for dropping voltages 6.3volts get hot i don't think they will handle +/-85vlts.

now i have to find the ttl ic 74hc04 series because the sn74s04n did not work in my case.

thank manoj for such a good amp

Hi stewin,

thank you very much for your appreciation.

for good low and mid use T106-2 0.8mm wire 59Turns.

use 3.3K/5w(75V supply) it will heat little but not burn

Hi stewin,

SN74S04N package is different (W package)

VCC= Pin 4
GND= Pin 11

Pin 1=1A, Pin 14=1Y
Pin 3=2A, Pin 2=2Y
Pin 6=3A, Pin 5=3Y
Pin 7=4A, Pin 8=4Y
Pin 9=5A, Pin 10=5Y
Pin 13=6A, Pin 12=6Y

My design using DM74S04 fairchaild one

Hi Manoj: I'm about to finish my one.

Hi: I have SN74HC04, will it work?

 

[stewin]

Hi: I have SN74HC04, will it work?

yes it will work . hadi used it and it his amp is o.k 🙂

 

[akraj]

yes it will work . hadi used it and it his amp is o.k 🙂

Just need couple of capacitors for amp board, 10p, 10n etc then it will be ready for firing up! I used IRF630 in power board hope this is okay as other version used 10N20!

Is the any issue if I use 10uF 16v capacitors?

Where to find aud600 parts at India

Hi Manoj: I would like to buy some IRS2092, high power MOSFET, inductors. Can you please let me know where in India I can buy them, Culcatta/Banglaore preferred.

Or any online shop in India to check price and availability.

Thanks
Raj

Hi stewin
i use 74HC04 for ver1.1
but it was not worked.
why ?

 

[aman khalsa]

happy new yeat to all my diyers.....

 

[stewin]

Hi stewin
i use 74HC04 for ver1.1
but it was not worked.
why ?

i got the ic sn74hc04n and it worked very well ver 1.1.please recheck your board .


happy new year diy audio world
and a happy and a prosperous new year

where specifically in board?

 

[stewin]

I'll gonna share my layout based on IRS900 / IRAUDAMP1.

I put the bias supply onboard and put an external OCP trigger so that the speaker protect will activate in case of short circuit.

Speaker protection circuit included.

Just don't remove my name when you etch the PCB. It gives me the credit for my effort.

Happy new year everyone 🙂

thanks jlister for sharing . but in the schema like the original ir900d you can't use +/- 65vlts or above comfortably . pls change the cd4049 stage to use three inverter buffer stage like irs1500 or aud ver 1 and 1.1 amps

 

[akraj]

where specifically in board?

I used 16V caps, marked with red circle.

HAPPY NEW YEAR GUYS

Hi Manojtm ,

Could you please start another topic for your design ? and if it's possible , move AUD600 related posts to that topic..

anyway , how can i have your amp's schematic ? because i want redesign board and change some component or their footprints etc.

Regards,
IRSound

Hi Raj,

Near IR2110 use 10uF/63v(for low voltage Max.55V) or 1uF/100V(for Max.90V)

all other which you specified can use 16v range.

Regards
MANOJ

Im new in Class D what does it mean to change CD4049 ? can you share schematic ?

I have this IRS 900 ,.. can work with + / - 80V or not ?
