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.
Solved! Go to Solution.
The Boost Converter is an option. So if customer would not use it, the external components are not necessary at all. The BST pin can be left floating, assuming the Boost option is disabled (by default bit GBOE = 0 in GDU Module Enable Register).

Any idea if the charge pump needs to be there even if the duty in software is saturated?
