7 / 37 page ![]() Cool-Power® Rev 1.3 vicorpower.com Page 7 of 37 02/2016 800 927.9474 PI354x-00 PI354x-00 Common Electrical Characteristics Specifications apply for -40°C <TJ < 125°C, VIN = 48 V, EN = High, VVDR = 5.1 V +/- 2%, L1 = 340 nH [1] unless other conditions are noted. [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.
