  • LM3880-Q1: Abs Max of FALG pin

    TI Thinks Resolved
    Part Number: LM3880-Q1 Hi I have a question about the pull-up voltage of FLAGx pin. At the datasheet, the recommend voltage of FLAGx pin is -0.3V~VCC+0.3V. However the abs max is -0.3V~6.0V. Is it possible the FLAGx pin is pulled up to 5V when the VCC…

    Part Number: LM3880 Hi, I'm a user of LM3880MF-1AA. I have two questions about "7.3.2 Incomplete Sequence Operation" in the datasheet. Q1. In Figure 7-3. Incomplete Power-Up Sequence, what are the maximum and minimum…

  • RE: LM3880: Push Pull Outputs version?

    Hi, Thanks, customer would like something similar to LM3880 better if p2p. I ask for additional information: which is the minimum low or high level of the EN pin to be recognized? If I had to generate a very short pulse of 1us on EN would it be caught…

  • TPS61175 + high side switch

    TI Thinks Resolved
    Other Parts Discussed in Thread: TPS61175 , TPS1H100-Q1 , LM3880 Hi, I am working on a circuit that has a +24 V switchable output (max. 1 A). The input voltage of +12 V is first boosted to 24 V using the TPS61175. Because I do not want +12 V at the output…
