  • TPS63020-Q1: Max output current vs. temperature

    TI Thinks Resolved
    Part Number: TPS63020-Q1 Team, Figure 1 from the datasheet shows the max output current vs. input voltage, but only for T J = 125 °C. Do we have similar graphs, e.g. 60 °C or 85 °C? Thanks, Robert

  • TPS63020-Q1: VFB spec

    TI Thinks Resolved
    Part Number: TPS63020-Q1 Hi, TPS63020-Q1's datasheet describes 2 kinds of VFB spec in P.5, one is at PS/SYNC = VIN and the another one is at PS/SYNC = GND. Why are the specs defined separately? PLS tell me the reason to separate and the reason why the…
