(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 < 0.1Ω.
