Note 1: All parameters reflect regulator and inductor system
performance. Measurements were made using a standard PI33XX
evaluation board with 3x4” dimensions and 4 layer, 2oz copper.
Refer to inductor pairing table within Application Description
section for specific inductor manufacturer and value.
Note 2: Regulator is assured to meet performance specifications
by design, test correlation, characterization, and/or statistical
process control.
