I have a question about the following model numbers (1) and (2) of the reference design provided by your company.
I think DCDC has voltage mode control, current mode control (peak current mode control), and current mode control (average current mode control) as control methods.
Which of (1) and (2) is voltage mode control, current mode control (peak current mode control), or current mode control (average current mode control)?

(The following is an excerpt from (2), p. 84)
4.5.2 Closed-Loop Performance To quantify the closed-loop performance, the following functional blocks have been implemented in the current design: • Sensing of primary and secondary voltages with the AMC1311 • Current sensing with the AMC3302 and AMC3306 • Temperature sensing with the TMP235 and LMT87 for addition possibility to protect power devices (not implemented in this design) These functional blocks are interfaced with the F280049 MCU, where the signals can be processed to implement voltage mode or current mode control. Currently, digital control has not been implemented in this reference design. This section will be updated following the release of this reference design with test results on calibration of signal chain, stability, and closed-loop performance of the converter.
