  • TPS53319: Output voltage at low load is lower than the design voltage

    Resolved
    Part Number: TPS53319 入力電圧20V,出力電圧3.8Vで使用しています。 出力電流2A程度で動作している時は出力電圧3.8Vで安定して動作していますが、出力負荷が低くなり、 出力電流が0.3A程度になると出力電圧が2.6V程度に降下してしまいます。 TPS53319は出力電流0Aから使用できる認識ですが、出力電流2Aの設計では出力電流が下がった場合、 動作が不安定になる事があるのでしょうか? また、本事象を回避する方法があれば教えてください。
