[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.}
