The other parts that get stressed are the snubber R-C components, hard to pick out without a schematic.

Silicon NPN Power Transistors
AS to the cooking switch transistor: I figured this is what blew the power supply. I checked both input capacitors ESR and found them to be at the datasheet max limit.
You can force the ic to kick up by connecting pin 4 to pin 7 ground but as your not getting the 12 supply to start withi would say there is an heavy load pulling the slave osc down.
Dec 26, 7 0. My ESR meter operates at kHz, if I find a cap with a published ESR for that freq on the datasheet is that a switchmode cap or is there another key attribute I’m looking for?
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 a slave smpu on the board to give the ic its 12v. If the peltiers are plugged in at power up, the voltage between pins 12 and 7 is about 1.
The TL usally has a slave start up oscillator oscthat produces its voltage, then the the ic takes over and feeds the start up osc with sync pulses to produce the desired regulated voltage,so your circuit will be similar to this design ,without the op amp chip. I do have a low budget scope, so I checked out pin 4. Oct 21, In this Teardown Tuesday, we are going to take a look at the inner workings of a radar gun! Ok, sorry it took me a few days to get this check done.

The ESR of the big caps is climbing with every troubleshooting attempt. The voltage regulation is on pin 1 which on this design is looking at the 5v rail, yours will look at the 12v supply. Switch Mode Power Supply Posted by zulkifli in forum: Oct 17, 2.

Sep 7, 2, Once I disconnect them the power supply comes to life. Your name or email address: I keep seeing alot if info regarding ripple current, but not ESR.

The relays are energized to remove power from the peltiers as necessary for proper cooling. Yes, datsheet password is: BTW, does the uF still gets hot, when everything is ok when you connect the peltier loads after sometime?
Is this a common problem with a SMPS? Also, I can’t seem to find the datasheet for these caps anymore. It’s also where manufacturers pinch pennies and buy cheap.
