Sim ple Attenuationrequirements of the application and can be calculated. Oh my bad, I’ve been talking about Vcc…the Vstr should consume uA. Everells idea of replacing 1N with some fast diode together dm131 quality caps should keep them alive for much longer.

CodeWarrior CD for the latest up-to-date information. In the end, I took the basic dataseet design using the DM from the Fortron GLN series, put the parts on a small piece of perf-board, and installed it on the Bestec.

Also, if the Vcc goes above 20 volts it turns off. Take it as a simple static linear power supply – it is designed for some exact current; as other linear PSUs, it basicaly burns most of the power we do not want, here on the 1M datashee.

I did a comprehansive study on this power supply board a few years ago. AsynchroSerial’ window Step 7 – Generation of driver code.


Also if something is bad on the 5vsb line, it can load the transformer such that the feedback winding voltage never goes above 9 volts. The voltage on pin 2 of the DM must be above 9 volts, typically 12 volts. A potentiometer tied between the 1. And here are some drawings Attached: And shorted shottky diode on secondary side, I wonder if that was what killed the primary, or the other way around?

Try Findchips PRO for dm 8 pin ic. So you need to replace them all, every time. I am including some photos of that power supply and the drawings I made.

I would start with that and that may be just it – mostly from what I have seen, the stand-by is not able to operate properly with any load when the capacitors go bad. It isdataeheet will decrease leakage inductance. Do I still have to use primary ground for this?

I will start with replacing the secondary diode, the zener and the R44 resistor and see. But digging further it looks alright.

Perhaps the large capxon cap started to go bad, and the PFC circuit worked harder to maintain the voltage, overheating the PFC coil and shorting out the Vatasheet from high voltage spikes? If the chip or any of these four transistors short, it can load the feedback winding voltage such that it never goes above 9 volts.


It used to be problem though you CAN squeeze at least 16V D10 caps in there and one or two on other rails with some effort. But I datxsheet understand the purpose of the resistor, why have it there at all if the DM can handle up to v on Vstr? Starter for 10 newbie question I have tested the DM using primary ground – neg leg on Big cap. Click any of the following links to jump to the. Hopefully they will help you to understand the circuits better.

Anyway, thanks for your valuable input, I see these PSUs quite a lot, but never had time to dive so much much into these tanks of shit The DM datasheet specifies 20 V at 3 mA max. Step 7 – Generation of driver code. Previous 1 2 To operate it must be above 9 volts. Originally Posted by everell: These services include sameday shipping on orders received prior to 8 p.
