Current sensing in DC-DC converter
I studied DC-DC converter in peak/valley/average mode control and I have a question about the methodology to sense the current in average current mode control. I saw lot of paper about DCR sensing but ...

Best approach for using multiple power monitors with single MCU (SPI)
I'm working on a project where I'm using several buck converters controlled by the same MCU (ESP32) and I will be adding a digital Power monitor to each converter. but I'm concerned about the number ...

Current sensing resistor placement [closed]
I will be adding a current sensing resistor to a Buck-boost DC-DC converter. Based on the IC datasheet, the resistor is placed at the low-voltage side next to the power inductor.
But, as far as I know,...

Why should the fullwave current sensor bandwith be about 10 times switching frequency?
This is an example of high side switch current sensor in a buck-boost converter.
I read that for high-side switch full waveform sensing the current sensor bandwith should be about 10 times switching ...

Using a switching DC-DC converter in high dynamic range current/voltage sensing
I'm thinking of making a power meter circuit which will have a high-side current-sensing amp (LTC6102), a resistive voltage divider for sensing the voltage, a dual op-amp (OPA2365) as a buffer for the ...

Placement of sense resistor on DC-DC converter
For my design I am using DC-DC converters LTM4620 and LTM4644, which integrate the MOSFETs and the inductor in the chip.
For measuring the output current, I will add a sense resistor in each output ...
