[1] All parameters reflect regulator and inductor system performance. Measurements were made using a standard PI33xx-x0 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.
[2] Regulator is assured to meet performance specifications by design, test correlation, characterization, and/or statistical process control.
[3] Output current capability may be limited and other performance may vary from electrical characteristics when switching frequency or VOUT is modified.
[4] Refer to Output Ripple plots.
[5] Refer to Load Current vs. Ambient Temperature curves.
[6] Refer to Switching Frequency vs. Load current curves.
