PI354x-00

[1]

All parameters reflect regulator and inductor system performance. Measurements were made using a standard PI354x evaluation board with 2.5 x 4”

dimensions and 4 layer, 2 oz 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. Output voltage is

determined by an external feedback divider ratio.

[3]

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

[4]

Refer to Output Ripple plots.

[5]

Refer to Load Current vs. Ambient Temperature curves.

[6]

Refer to Switching Frequency vs. Load current curves.
