I am using buck converter. 3.3V output & 2.5A part with 2.1MHz switching frequency.
I am powering my microcontroller with this 3.3V output. So, I'd like to find the output voltage tolerance of the buck converter.
Usually, to find the min and max output voltage of the converter, there would be some output voltage formula which would involve some resistors. So, I would take these resistor tolerances that would help me find the minimum and maximum output voltage.
Since, there are no feedback resistors in the the 3.3V output configuration, or any other formula, can someone tell me how to find the minimum and maximum output voltage for this part?
I am also using a 10uH part as inductor with 2x 10uF capacitor. Can someone also help me on how to calculate the output voltage and output ripple current? There are no calculated examples or formulas provided in the datasheet. Please help with the above.
