9 / 42 page  Cool-Power® Rev 2.0 vicorpower.com Page 9 of 42 02/2016 800 927.9474 PI33xx-x0 PI3318-x0-LGIZ (1.8 VOUT) Electrical Characteristics Unless otherwise specified: -55°C < TJ < 125°C, VIN =24 V, L1 = 155 nH [1] [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, 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. [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.
