That the voltage(0-100mV) is added to SLOPE of STCS05A, an electric current, variable, is it possible?

Has anyone worked their way through the design calculations for the AN5287 Application Note, " 170W high input voltage two switch flyback based on L6565 and 1500V K5 MOSFETs"? When I work through their formula I cannot get the same results?

Isolated Low-Power Capacitively Coupled Supply

Hi Guys, I'm designing a low-power isolated supply (3.3V, Max ~50mA) and am keen to steer clear of transformers as EMI is critical to the design and I've had some noise issues with my previous transformer-based design. I have been looking at using a ...

GPIO vs SPI for LED1642GW

Well, as you can see in the datasheet and the application note for LED1642GW, It doesn't use pure SPI, since it doesn't use CS but it requires the Latch Enable (LE) signal.I'd actually like to write an application to manage multiple LED drivers but t...

What is the input impedance of COMP pin of L5991? I need it to compute feedback loop gain of a flyback power supply.

I'm designing a insulated 45V 54W flyback power supply using L5991. Feedback is closed via TL431 and an optocoupler, as in figures 33 and 34 of datasheet. To compute the loop gain I need to know the impedance of COMP pin but I don't find it in datash...

L9916 OTP programming problem

Hi,I am use L9916 for alternator project. I want to do OTP programming. but I could not succeed. I found only one document for programming. There are some issues that are not fully explained in the document.Field monitor pin, understood as the pin ca...
