Unless otherwise noted, measurements taken on the TPS23882B EVM and Sifos PSA-3000 PowerSync Analyzer with PSA3202 test cards. Test conditions are T_J  = 25 °C, V_VDD = 3.3 V, V_VPWR = 54 V, V_DGND = V_AGND, DGND, KSENSA, KSENSB, KSENSC and KSENSD connected to AGND, and all outputs are unloaded, 2xFBn = 0.  Positive currents are into pins.  R_S = 0.200 Ω, to KSENSA (SEN1 or SEN2), to KSENSB (SEN3 or SEN4), to KSENSC (SEN5 or SEN6) or to KSENSD (SEN7 or SEN8). All voltages are with respect to AGND unless otherwise noted. Operating registers loaded with default values unless otherwise noted.
