The IOUT_CAL_OFFSET offset value is simply summed with the READ_IOUT data, so it’s pretty straightforward – except the encoding is non-complaint to the PMBus standard. The IOUT_CAL_GAIN is not compliant…
For the no-droop operation, start with R2/R1 ratio between 1 to 3. Choose R1 between 400Ω and 800Ω, then adjust R2. Final value of R2 may need several iterations in order to put the crossover frequency…
With a DC load line (DCLL), a buck regulator will essentially present itself as a fixed resistance to the output load.
In a circuit where there is a 150A load being pulled by an ASIC for example, at…
First and foremost check the connectors you are using between your design and the load's positive and negative terminals. Although on the board you may be measuring a 1V output, even a 1mOhm resistance…
It is the load line of the DC equivalent circuit. It can be determined by reducing the reactive components in a circuit to zero (capacitors to open-circuit and inductors to short circuit).
With a DC…
Q1) How many times can the STORE_USER_ALL command be executed (to save the user configuration inside the OTP)? Answer: Up to 4 times. Q2) Is the max-4-time write limitation for the OTP applicable to the…
The input voltage should be measured on the board itself. It can be measured either at the input terminals or across the input capacitors. In a high power design there is a significant amount of input…
