Measurements were made using a standard PI33XX 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. Note 2: Regulator is assured to meet performance specifications by design, test correlation, characterization, and/or statistical process control. Note 3: Output current capability may be limited and other performance may vary from noted electrical characteristics when switching frequency or Vout is modified. Note 4: Refer to Output Ripple plots. Note 5: Refer to Load Current vs. Ambient Temperature curves. Note 6: Refer to Switching Frequency vs. Load current curves. |
