Can someone route this pcb for me. I think i will struggle with it, so if anybody can help me here
I am attaching the schematic and the board file

Thanks for the reply. Realized i should try a little more before getting it done from someone
How much will it cost if i get it done ? Will a single sided pcb for the same ckt cost more or a double sided one ? Pcb routing looks very difficult, but i am trying it .
I have started something , so wanted to also know how to go forward with the routing.I am attaching a image of what i have done so far. Here i have a SOIC-8 package MOSFET driver, a smd inductor and smd capacitor

Hi vinay,
better make it double side because SMD components is used.give the schematic in orcad file format. i will try it in single or double side.double side is costly compare to single side. if you want PCB in single side better use Through hole components.it is easy only

I have already bought the components and three of them are smd, so ill have to use them only now. As you have said i have made a schematic in orcad capture Cis lite. The components used in the schematic are just to show the connections and they do not have footprints associated with them.
I have the pspice .lib files for them except for TPS2833 and none of them has layout attached in the model.I am also attaching the datasheets of the components in case if you require. I had created the foot prints for the components in eagle but i dont think they will be any use in orcad ?
The MOSFET used is PSMN1R1-30EL from nxp ----- I2PACK
Inductor ------MLC1560-901ML from coilcraft---900nH-- dont know its package
Capacitor----- CAPACITOR, CASE D, 680UF, 4V
Man. Part No.:T520D687M004ATE012
The Mosfet driver---TPS2833D---SOIC-8
------------------------------------------------------------------------------------
Need connectors at IN(inputs of TPS2833) and connectors for power supply(12V) and to connect load across capacitor

hi vinay,
i have one doubt in that i marked in red color rectangular box.is it battery ?? i think it is connector for input supply ,right ?please send the part no ?? for capacitor which (smd) package do you want ?

It is a very simple design ... you should also try it yourself dear..........you will have fun during the process..... believe me

Your post does not have any attachment, so i am guessing that what you have marked is the battery used in the schematic.Yes in place of the battery i need a connector for 12V supply. A normal connector to connect a bench power supply.Like the one showed in the url https://www.ebay.com/bhp/lab-power-supply.Or even jumpers will also be okay.I can then connect power supply with wires

I dont know what is the package the KEMET capacitor comes in or if case D is some sort of package ? In eagle i made the footprint using the datasheet

Yes i did try it. And also routed it completely using eagles auto router .I have attached the final thing. I just started pcb design and this is my first work. And to route a power supply with smd components, i will have to learn a lot of things.

Kapil please tell me too how do i identify the package of an smd capacitor ? The datasheet of the capacitor says its case D . Is case D a package ?

Case D is an IPC standard size. Refer to ipc standard document.
you can also follow the datasheet if you know the part number..

yes case D dimensions are there on the datasheet.So is case D the package ?
 

Yes. it is the package size...
 

A pdf of the schematic would be nice.
The layout above is terrible, the components are spread all over the place and no thought for return current. You have a lot to learn, especially if it is a SMPS design, not the best sort of design to start on, it is rather specialised, unless you want a lot of noise and problems.
 

Hi vinay,

please check the layout file in allegro (you can download the allegro viewer through cadence link: **broken link removed**)

Hi vinay,
if you gerber file(fabrication file) i will send to you.please look at the PCB if you need any clarification let me know.

Are the light green spots on the pcb the connectors ? Is it single sided ?
Sorry kapil for not being precise on the first instance. could you incorporate certain changes here
There is only one smd capacitor C1 (C1 from layout). Other caps are not smd they are through hole, also the resistors connected to the driver are through hole
Also a few connectors(to connect jumpers) are required.I am attaching a schematic with the jumper positions.

Hi vinay,
it is double side board only.i could not understand where you want connector better mention in layout.for Through hole capacitor part no ??

I have attached the schematic again now the the jumpers on it.And the capacitor part no is CPOL-EUE2.5-6

Thanks

Hi vinay,
i could not find the datasheet for particular part can you send the datasheet and which manufacturer ??

hi vinay,
i complete the board please check( i assumed the through hole cap) please check the datasheet with footprint if it is match leave it or else send feedback.if you want gerber i will send to you
