Hi sir manoj
good morning every one
this is AUD600 class D amp ver 1.1 from sir manoj
this is not complete yet

Hi Hadi,
Very nice work,thanks
ETD29 you have horizontal type.my pcb pad is for edt29 vertical type.and one micro switch you connected for what??

Hi sir manoj
thank you
the micro switch is just for test .
i mean thermal test.
i must change the board for my component a litell.
i can find 330 and 370 uH self
can i reaplace them with 220 uH ?
i can not find 6.3 V zener diod. i use 6.2V zener. is this ok ?
what about the gap ?

aud600 vs irs900d
hi manoj . your amp has many components compared to irs900 . is there any advantage in terms of noise or thd over the irs 900d?

they all share similar design. output power scales with the rail voltage. irs3000d uses stacked inductor to increase power rating.
Hi Hadi,
use min. 22uH and Max.220uH for reducing emi and AC50Hz line noise.(recommended 68uH)
ok use zener 6.2V
1mm gap all
why you are waiting for 1K 1% resistor for testing use 1K 5% one

Hi stewin,
all are self osc.(delta sigma modulation) type class d. my design is low emi and low noise one

Manoj
Hi stewin,
for low THD use MOSFET 70/100nc one gate resistor use recommended the manufacturer
use fsw = 400KHz/450KHz to get smooth sine wave (that will reduce filter size and capacitor value)do not compare with 250KHz range.
for class d start with 80KHz to 500KHz.(new generation MOSFET) for 100KHz use big filter ie. @300uH and big capacitor ie. 30uF/250V to reduce noise and wave shape comparatively good
fsw = 400KHz filter @22uH capacitor 0.47uF/2250V to achieve this you need good PCB, supported MOSFET, good filter and components.
for DIYs start with 125KHz (it is easy) and try with 250KHz switching(not easy)
My design you can go up to 400KHz range
Regards
MANOJ
Hi hadi,
for output filter ? No. for fsw=@250KHz use max 90uH. good 62uH or 70uH
fsw=@180KHz or 150KHz you can use 170uH filter
for DC filter yes you can use 170uH
Regards
MANOJ

you use 3 pcs 220uH 1/4w self in your pcb
one in power and two in amp.
i was said can i replace 170uH with 220uH in your board ?
thanks
