Sprrogy MK3.0 coming soon.!!!

Mastero · 08-25-2003, 05:40 PM

Hello friends ,

Just completed the MK3.0 design. and received the PCB for it. shall test it in the next 24hurs and post the result here with ALL details.

Spec:

3.3vdc --- 5amps
5vdc -----10amps
12vdc-----2amps
-5, -12, stby everything on ... full ATX features......

"NO MORE t6"

ISOLATE THE MBR745 AND THE MTP3055 ON THE HEAT SINK

CHANGE THE IN5819 TO IN5822 SORRY ABOUT THAT.

Cheers

does that mean the parts will be easier to get?

how much of the old parts can be used witht he new setup?
i got a few of the parts just never got the rest of them to finish the older version

Please wait for a while shall post all details up here with components list

Hi from Spain, Do you like it?

Description/Specifications
Dimensions (mm) 160 x 45
Input Voltage Required (V) 11.4V~12.6V
Maximum Output (W) 62.4
Output Voltage V 5VSB +3.3V +5V +12V -12V
Current A 1.5 4.0 4.5 1.5 0.1
Power Output W 7.5 13.2 22.5 18.0 1.2
Peak Current A 2.0 8.0 8.0 2.0 0.2

I have got one unit and is perfect to mount in a car. Price 30€.

Taluego...

Your car voltage will go up to 14.4V, thereby breaking the input voltage requirements. This is not very suitable for car use without a regulator on the input. This has been covered many times before.

Marvellous, give us an update ASAP please Mastero

But with a lm78L12 I can regulate the voltage to 12v. It works to me perfectly. Hasta luego

Rob Withey · 08-26-2003, 11:21 AM

The 78L12 is a 100mA regulator, which is not enough. In addition it is a linear regulator (and requires the input voltage to be higher than the output by about 2v). Again, this has been covered many times before, I'd recommend you do some reading.

mikeinsanmarcos · 08-26-2003, 11:48 AM

Yes, it does work, provided you dont run any 12 volt accessories. Running a regulator will drop you down to some pretty scary voltages which could give you some equipment problems down the road.. I had this setup just to see how it worked and my biggest complaint was that it will not ride thru starting up your engine, this is a major pain... Not a bad cheap solution, but not perfect..

With a 100mA regulator, I think not... <flap flap oink>
With something more beefy, yes (with the problems you indicated).

yah, you are right rob.. I think I was using four LM2940 12 volt 1 amp regulators to power my setup..

hey guys ... I was talking about a new Sproggy ... where have you taken my post ....

you think this new PSU should be called something on the order of the MasteroPSU 1.0 ????

i mean, you basically redesigned the supply... right. i give credit to sproggy for the original designs, but i think you might deserve a bit of "naming rights" as well.

mp3z24 its a nice taught, but you ses the name "sproggy" is like a brand and everyone in this feild knows what they are looking at.

I like to keep it this way. Ofcourse on the PCB there will be mastero written also
