In audio D amplifier, if they are in single-ended mode and they use a single-supply we need to use a DC-blocking capacitor. Otherwise we don't. Why is that?
I know that, for a buck converter if the Output voltage is constant and the load current increases, the efficency should incresse. But after a certain value of the output current, the efficency starts decreasing. Can somebody tell me why ?
Guys i'm designing a pcb on fusion 360. I need to use a component which is not in the fusion library. So i added the library for the 2d and footprint model but i don't know how to add the 3d model. Because the 3d model is in another file
Guys i need to find a buck converter whose output is going to be connected to an ADC (ads131b26-q1). Basically the ADC datasheet says that i can use just the pins APWR and DPWR with and input voltage between 4 and 16 V. the problem is that i don't know which is the maximum current that i can...
Thank you so much

And what about the 5*100 nF + 1*4.7 uF ? should I use 5 capacitors of 100 nF and one capacitor of 4.7 uF? Because there are three pins in my model for VDD. So i don't understand
In this datasheet there is power supply scheme. I have a few questions:
1) Why do they write 10 nF + 1 uF ? Or 5 * 100 nF + 1*4.7 uF?
2) what kind of capacitors should i use in the real circuit ? electrolitic? Ceramic ?
I need to design a buck converter with Vin=12 V, Vout=5 V and Maximum Iout=10 A. Do you have any suggestions on how to choose the mosfet and the diode ? And specifically, what kind of information I should look for on the datasheet?
yeah exactly i've asked myself the same question and i don't know what to say. the guideline says to design a buck converter with a microcontroller which processes the output from an external ADC and generates a PWM signal for the MOSFET driver. The ADC requires output voltage data from type III...
Suppose I have a buck converter with an output voltage of 5 V and a maximum output current of 10 A. I need to send this signal into an ADC with a Type III Compensator.
This is the input voltage range for the ADC (i'm using the ADC3A)
Now i have to design a Type III compensator shown in the...
