Note 1: All parameters reflect regulator and inductor system
performance. 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.
Note 7: Minimum 5V between Vin-Vout must be maintained or a
minimum load of 1mA required.
