Dec 17, 2024 · I made a simple smps with uc3845. The output of the ic is connected to IRF840 and a EE30_15_7 ferrite transformer wound by me. The osc section seems to be working. Vcc supplied is …

Nov 8, 2024 · I'm trying to turn a Boost into a Flyback and then into an audio amplifier. Basically I wanted a simple SMPS modulated with an audio signal. I know, you will say that the class D amplifier is also …

Dec 17, 2024 · For the SMPS stuff, a 100MHz CRO is usually good enough and there are some newer CROs around that have mutlichannel digital inputs you can use for all manner of digital circuit tests …

Jul 2, 2024 · Prior to making a solid connection between the SMPS negative output terminal and "actual earth ground." I suggest measuring the voltage between those two points.

Aug 10, 2024 · Pls. Help SMPS output low... 6.62 volts instead of 20 volts. No shorted components no dried up caps. Uc2844 not shorted...
