(Note 3) For capacitance of input capacitor take temperature characteristics, DC bias characteristics, etc. into consideration to set minimum value to no
less than 4.7μF.
(Note 4) For capacitance of bootstrap capacitor take temperature characteristics, DC bias characteristics, etc. into consideration to set minimum value
to no less than 0.047μF.
