[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.}
[7] _{Minimum 5V between VIN-VOUT must be maintained or a minimum load of 1mA required.}
