[a] All parameters reflect regulator and inductor system performance. Measurements were made using a standard PI352x evaluation board with 3 x 3"

dimensions and 4 layer, 2oz copper. Refer to inductor pairing table within Application Description section for specific inductor manufacturer and value.

[b] Regulator is assured to meet performance specifications by design, test correlation, characterization, and/or statistical process control.

Output voltage is determined by an external feedback divider ratio.

[c] Output current capability may be limited and other performance may vary from noted electrical characteristics when VOUT is not set to nominal.

[d] Refer to Output Ripple plots.

[e] Refer to Load Current vs. Ambient Temperature curves.

[f] Refer to Switching Frequency vs. Load current curves.

[g] Contact factory applications for array derating and layout best practices to minimize sharing errors.
