Stability for Op Amps Part 8.pdf See attached Part 8 of a previous article series. Note the closed loop transfer will be different for inverting and non-inverting unless in non-inverting you tie input noise gain R-C circuit between +input and -input of…
Ravi,
Op amps are NOT best suited to be used for zero-crossing detector due to its relatively low slew rate and long overload recovery time (output coming out of rail).
In the case of OPA379, not only the typical slew rate is just 0.03V/us but more…
HI Sumit,
The Vout of buck concerter can be roughly calculated as Vin*D, where D is the duty circle.
To get some margin, I think you can convert 12V-50V to around 9V, then use 9V to generate other low voltages.
TPS40170 can be used to convert 12V…
Hello Madhu,
There are several methods of phase detection. A simple method would be to subtract the analog signals to get a signal that its amplitude increases with increasing phase difference. But that would require both signals to be analog and equal…
Hi G Cant,
To the reduce the spike, you can refer to the simulation model.

And you can also refer to the Datasheet P11 to P13, there…
Here are a couple of Power Supply Design Seminar papers that may help you. There are two papers combined into one pdf so that I don't have to use two seperate posts.
This comes from small signal model of the PFC power stage. This is well known in industry and has been used for many years. Please read related literature on PFC control and you will understand this principle. FYI, I am attaching one of these related…
I assume the system blocks upload of .xlsm file type.
Please check if below can help.
