Hi,
the Chinese site did not help much. But I have now figured out what kind of filter I need to design. I need a filter with a common-mode choke that dampens the common mode noise. Then I also need a LC filter to suppress the differential noise from the LM2576 and also my internal DC/DC...
Hi,
have run into some problems. I need to design a power supply for 24V dc 1amp. The problem is that it needs to fulfill a lot of standards. The device that has the built in power supply needs to be classified for use on ships. I need to fulfill the following standards.
IEC 61000-4-4 Fast...
Hi,
thanks for the tip, got me searching in a new direction. The op amp solution is not really suitable for my application due to the space. But I found a circuit named MC33161. This is a universal voltage monitor. I am going to use this one. I was also in need of the big temperature range -40...
Hi,
I have product that have dual redundant power supply. But I would like to have a voltage OK led.
The power supply can take 7 to 50 VDC input voltage and gives out 5VDC. I now only have a led connected to the output of the power converter. But if the input voltage goes below 7VDC the led...
