Note 1: Derate at 0.8 mW/oC for operation above TA = 25 oC ambient tempera-
ture, when heat conducting copper foil path is maximized on the printed circuit
board. When this is not possible, a derating factor of 1.6 mW/ °C must be used.
Note 2: The output regulation threshold, VOUT(REG), is guaranteed-by-design to
be independent of the load. Regulation will occur provided that the load current is
within the capability of the converter, IO(MAX). The output voltage may fluctuate
slightly with load due to the variation of the ripple voltage, whose magnitude is
primarily determined by the inductor and the ESR of the output capacitors.
Note 3: Maximum load current depends on inductor value. With a 0.9 V or 1.0 V
supply voltage, 4 mA can be obtained with a smaller inductor value.
Note 4: Converter efficiency is a function of the diode forward voltage and
inductor winding resistance. It may also depend in varying degree on the inductor
value and capacitor ESRs. By trading component size for better specifications,
efficiency greater than 80% can be attained.
Note 5: Test performed using the test circuit below.
