Some questions about MPM3695-10

DC-DC Power Converters
1
  1. What happens when the voltage of REF is set over the range of chips?
  2. How to calculate the output capacitance?The value of the internal inductor is unknown.
  3. Does it support burning FW and how many times? Will it be restored to the initial voltage after restart?

Hello,

  1. Not sure if I am understanding the first question correctly. Are you asking about Vref going above its range?
  2. The value of the internal inductor can be found on the block diagram on page 17.
  3. With the MPS GUI, you can configure the parameters and upload to NVM. I’m not sure how many times it can be written, however, on the top right corner of the GUI it shows how many remaining write cycles in NVM. Once it is written in NVM, it should remain to the set configurations even after a new power cycle.

Here is the link to the GUI: Virtual Bench Pro 4.0 (monolithicpower.com)

Here is the datasheet for more information about the part.

  1. Yes. The REF voltage is equal to VOUT_COMMAND x VOUT_SCALE_LOOP. For example, if the VOUT_SCALE_LOOP to is set to 0.32, and the VOUT_COMMAND is set to 2.5V undesigned. The REF voltage in the equation will be 0.8, over its range. What will happen to the circuit?

What resistor values are you using?
Following the information in the datasheet on page 21 should give a REF voltage within the range.
