  • RE: TPS7H1111-SEP: Current Limit vs Input/Output Differential Voltage depending on temperature

    Resolved
    Hi Hirano-san, Thank you for your patience. I understand that this feature is somewhat vague and confusing. Figure 6-14 only applies when VOUT is 100mV below its programmed value, such as during startup or during a heavy load fault condition. The…

  • TPS7H1111-SEP: LTspice symbol creation error: undefined subcircuit nmos_1111

    TI Thinks Resolved
    Part Number: TPS7H1111-SEP Hello, I’m simulating the TPS7H1111 in LTSpice. I’ve done the usual symbol creation and when running the simulation I get an error. I’ve found the nmos_1111 in the .lib file of the model on line 116, it is the only place…

  • TPS7H1111-SEP: Simulating output offset voltage when current sharing with two parallel devices

    Part Number: TPS7H1111-SEP Other Parts Discussed in Thread: PSPICE-FOR-TI Hello. I'd like to simulate two parallel TPS7H1111-SEPs in PSpice for TI. Using your TPS7H1111 Pspice model, I can't see an obvious way to configure the output offset voltage, to…

  • RE: TPS7H1111-SP: calculated Rfbpg_top vs spice simulation

    Hi Erik, I'd like some clarity on the following because the output voltage is configured by SS_SET: Is the expected output voltage seen when not using the Rfbpg_top value calculated for 90%? i.e do you see the expected output voltage when using…

  • RE: TPS73801-SEP: TPS73801-SEP for output voltage of 1V

    Hi Thorsten, The TPS7H1121-SEP or TPS7H1111-SEP would be Space Enhanced Plastic options for a 1V output. Thanks, Sarah
