  • TPS63900: CFGx Resistor Precision (Output Voltage Configuration)

    Resolved
    Part Number: TPS63900 Tool/software: Hello, I was just wondering if CFG1-CFG3 allows any tolerances for the resistor values. For example, to configure V OUT we should select R CFG1 = 36.5 kΩ and R CFG2 = 511 Ω. Will the TPS63900 work reliably when…
