The NXP® Flyback SMPS Design Tool helps you design flyback power supplies using NXPs TEA172x, TEA173x, TEA183x, and TEA193x family.

Hi Atom FWIW.leave SMPS design and everything to pro's. Don't go and meddle. Drajver virtualjnogo com porta dlya usb printera. One day I will maybe tell you a story about how you can burn your fingers. And waste money. And 'design a SMPS'. Repair is hard enough.design is impossible.

A 'dark art'. A little caution here from a Dude that has traveled that rocky road. And absolutely hates **** SMPS designs. And applauds good ones.

Problem is the good ones don't break.so you never get to know them. And the shitty ones you fix all the time become your bread and butter. Thinking back now and with all I do daily with cheap TV repairs.well designed SMPS are a boss. Still, on any SMPS no matter how brilliant the design, the weakest link is the Main Smoothing Cap. If it pops, all goes to hell. On a TV.hum bar.

On other things, not really noticed. Until the SMPS decides to die too.

My SMPS cautions to people are well founded. Unfortunately they are the future. I really don't know what else to say except a more Linear approach????

Maybe a mix of Linear and SMPS??? Hi Atom Search the NET then. And see what you come up with. Nobody likes to touch SMPS.they are bad boys.worst part is wanting to build one without understanding what you are doing. By the way, I have around 94 Viper 50's for sale.

I used the original Viper software from ST. Detailed instructions of how to make them fly.that was around 2001. After blowing five up.only one unit cut it. And it was good until one day it blew up too.

My chopper transfomers came from NZ. Nobody here new what I was on about. So, as a guy who has been through the stuff, leave SMPS alone. You WILL burn your fingers by trying to build them. The chopper Transformer is the Boss of a SMPS.

Here is a Samsung LCD TV Circuit Schematic as an example. When troubleshooting your Television you will need to use schematics and diagrams to pinpoint the issue. The information that i'm talking about is LCD & LED (3D) TV Training Manuals, Schematic/Circuit Diagrams, Service Manuals, Service Bulletin, LCD TV Firmware, LCD Inverter Information, IP & PSU Schematics, Understanding SMD Components Codes, MCU file and many more. Introducing the LCD & LED (3D) Tv Repair.

You have to get it right. Sidenote: My Viper 50's will be worth a fortune one day.

Holding onto that dream Regards, tvtech. We could not get the Chopper Transformers wound correctly with consistency. The Viper software showed how the PCB layout must look. I followed it to the letter. Picture perfect. ^^^ Atom, don't kid yourself. Believe me.I(We) tried.

And I do not give up easily. Think about this: Not your normal Mains transformer running @ 50/60 Hz that can be wound easily. Other things to consider: 1. Core Material.

2.Switching speed(dealing with around 100 Khz here). And yes I said 100Khz.

So much quick switching, so much happening.in the blink of an eye all goes to hell/heaven. It's not ST's fault. There are literally thousands/millions of these out there still. Reliable as ever.

I did not know enough then. Could not get the SMPS Transformer wound correctly. And that is that. And a lesson learned. Typical of me though.always trying the cutting edge And all this took place around 2001 or 2002. I have changed though.sort of like mediocrity right now.instead of trying to lead.I shut up and listen rather. And try and prevent others making my mistakes.

Saving you time. Saving you money. Regards, tvtech.
