(1)The supply current is twice the output short-circuit current.
(2)The converter regulates by enabling and disabling periods of switching cycles. The switching frequency is the oscillator frequency during
an active period.
(3)See efficiency curves for other VIN/VOUT configurations.
(4)Effective Series Resistance (ESR) of capacitors is < 0.1
