What role does the inductor and output capacitor play in a buck converter? [closed]
What role do inductors and capacitors play in buck converters?
I know it acts as an LC low-pass filter.
What other role does it have? When the switch opens, does the capacitor discharge in the load? ...

Buck-Boost Converter Inductor Value
I am designing a typical buck-boost converter using the LTC3530EMS#PBF IC from Analog Devices.
My design specs are as follows:
Vin: 3.0V - 4.2V
Vout: 3.3V
Iout(max): 300mA
Fsw: 1MHz
In the datasheet, ...
