[1] When output is set to > 2.6 V, the output follows the input down when VIN gets near 2.8 V.
[2] The higher output voltage available depends on the voltage drop in the conduction path as given by the following equation: (VINSW3x − VSW3x) = ISW3x

(DCR of inductor + RONSW3xP + PCB trace resistance).
