No load.
Maximum output current measured when output voltage droops 100 mV from the programmed target voltage with no load
present.
Because the internal linear regulators are cascaded, it is not possible to simultaneously operate the V

following two conditions are met:
DCDC Double FETs Enabled, Inductor Value = 15 μH.
The DCDC Converter is a triple output buck converter. The maximum output current capability of each output of the converter
is dependent on the loads on the other two outputs. For a given output, it may be possible to achieve a maximum output current
higher than that specified by ensuring the load on the other outputs is well below the maximum.
Assumes simultaneous load of IDDD = 250 mA@ 1.55 V and IDDA = 200 mA@1.8 V.
