No, create an account now. Output pulses on pins 8,11 feed the slave datasheeet transistors 2sc, they self oscillate at first pulsing the transformer on the right, which feeds the 12 dc supply back to the ic on pin 12 to take over.

Yes, my password is: I also noticed that, once up and running, one of the heat sinked power transistors and its associated V uF input cap is getting very hot.

Your name or 2sc33306 address: Switch Mode Power Supply Datassheet by zulkifli in forum: It shows about 1. I’d like to check the ESR again since the overheat. Dodgydave – Yes, it is a 12V output supply. Could this be causing the problem?


Switch Mode Power Supply

I disconnected the peltier coolers and everything comes to life. As soon as the peltiers are datasjeet the voltage jumps to 12V and the rest of the unit powers up fans, LCD, etc It seems to be getting worse. Can anyone tell me what type of SMPS this is?

Oct 18, 9. Dec 26, 7 0. Jun 22, 7, 1, I also look for resistors that are darkened from heat, don’t see any in your picture. Are these related somehow? Also, I can’t seem to find the datasheet for these caps anymore. The voltage regulation is on pin 1 which on this design is looking at the 5v rail, yours will look at the 12v supply. Oct 18, 6. I checked both input capacitors ESR and found them to be at the datasgeet max limit.

I found one fan that was drawing much more than its rated current and not turning. Same result with another 1uF cap datasheet paralell. The fans are wired to run all the time.

Usually with this type of psu, there will be a delay to get the 12v up working, then it will power the peltiers, there must be datashest slave smpu on the board to give the ic its 12v.

Anything else I should look at? You May Also Like: I do have a low budget scope, so I checked out pin 4. In this Teardown Tuesday, we are going to take a look at the inner workings of a radar gun!

Fatasheet Powered Security Light In this teardown, we will look at the internals of a motion-activated light which contains its own solar charging system. As soon as I get the lager caps in I’ll change them all just in case. Quote of the day.

Oct 18, 8. Sep 7, 2, Oct 18, 7. Electrolytic caps are BY FAR the 1 component failure in cheap switcher power supplies because they have high peak currents rushing in and out at high frequency.

I figured this is what blew the power supply.
