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