6.5 Electrical Characteristics

Conditions are –40 < T_J < 125°C unless otherwise noted. V_VDD = 3.3V,V_VPWR = 54V, 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_SENSE = 0.200 Ω, to KSENSA (SEN1 orSEN2), to KSENSB (SEN3 or SEN4), to KSENSC (SEN5 or SEN6) or to KSENSD (SEN7 or SEN8). Typical values are at 25°C. All voltages are with respect to AGND unless otherwise noted. Operating registers loaded with default values unless otherwise noted.
