What are the essential considerations of a BUCK converter with a battery(lead-acid) as a load? Here are some basic questions which i need some clarification:
1.Is it better to use a synchronous buck(free-wheeling diode used) or a non-synchronous buck(free-wheeling diode replaced by a FET)?
2.Is there a requirement of the output capacitor,as the battery itself would act as a large capacitor in this case.
3.Assuming that the step-ed down voltage is always greater than the battery voltage,How to calculate inductor value which would ensure continuous current flow from the BUCK to the battery,in order to charge it.
4.Would it be better to user a low side shunt or a high side shunt to monitor charging current.
