Hi,

 

The customer does not require Boost section as the power supply is regulated and would never go below 10V. Can the L, C, D associated with boost be completely avoided. Does he need to take care of anything else.

 

Also for the charge pump, customer saturates the duty cycle at 90% which means he would never be working on 100% duty cycle. Is it safe to say that the combination of C & D for charge pump section can be removed? Does he need to take care of these power pins of MCU in any special way.
