  • LM2698: Vin =+5V Vout = -15V, not supported by WEBENCH

    TI Thinks Resolved
    Part Number: LM2698 I am looking to design an inverting boost DC-DC going from Vin = +5.0V to Vout = - 15V. Because of part procurement difficulties, I am trying to use the LM2698 since it seems to be able to do it. WEBENCH does not support the inverted…

  • LM2698: LM2698

    TI Thinks Resolved
    Part Number: LM2698 Hi , We are using LM2698 in our design. We are boosting 7 to 8 V to 12 V. Our circuit was working fine. Load on 12V o/p is max 100mA. Below is snap of our circuit. While testing suddenly chip started becoming hot. We then isolated…
