PRODUCTION DATA

6.6 Typical Characteristics

Conditions are –40 < T_J < 125°C unless otherwise noted. 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). 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.
