Features and Benefits 

The MPM3695 is highly customizable. Users can program the power module via the MPS PMBus and 
multi-time programming (MTP) memory.

 

Values written to the registers via PMBus will NOT be retained once the module is powered-sown 

unless they are written into the MTP memory 

To write to the MTP memory, the input voltage must be greater than 8V. 

The key programmable features are highlighted below: 

 

Current limit

 

 

Switching frequency

 

 

Operation mode 

– pulse skip mode (PSM) or continuous conduction

 

mode (CCM)

 

 

Output voltage

 

 

Soft-start time

 

 

Fault threshold
