使用TLV62565,5V轉3v3,輸出的Vfb、Vout與預期不同。

Other Parts Discussed in Thread: TLV62565

請問使用TLV62565,5V轉3v3,使用120K+549K,照模擬網頁的結果(https://webench.ti.com/power-designer/switching-regulator/customize/1 ),應該會得到約3v3的數值,但實際出來的值會是4V左右,請問是犯了什麼設計上的錯誤?又或是該如何找出錯誤?  其相關資料如圖所示。

有嘗試把L2電感移動到IC旁連接SW與3v3位置、並且將R3、R4直接靠在FB上再跳線至3v3、GND,但輸出還是沒太大影響,還是4V。
