    Part Number: LM5122 Other Parts Discussed in Thread: LMV431 Tool/software: Hi TI Team, I follow TI's circuit and apply in our design for Over Voltage protection, in Vout=54V application, R1=10k (PR191) , R2=453K (PR192), OVP setting point should be…

  • LMV431A: Hysteresis on AC Voltage Detection Circuit

    TI Thinks Resolved
    Part Number: LMV431A Other Parts Discussed in Thread: LMV431 Hello, We're trying to create an AC voltage detect circuit using the LMV431, but are seeing considerable hysteresis in PSPICE simulation. We would like to see is the RED trace go low when…

  • LM5117-Q1: SNVA829 Figure 3 FB pin voltage

    Resolved
    Part Number: LM5117-Q1 Other Parts Discussed in Thread: LMV431 , LM5117 I plan to implement a CC/CV regulator very similar to Figure 3 in SNVA829. One thing that I am concerned about is the absolute maximum voltage on the FB pin. From the Figure 3 schematic…

  • LM5117: Output voltage is lower than expected

    TI Thinks Resolved
    Part Number: LM5117 Other Parts Discussed in Thread: LMV431 , TLV431 Based on the SNVA829 app note, I designed the CC/CV converter for the input voltage of 60V and output voltage of 50V@14A. While testing the design with no load, the converter only outputs…

  • LM5023: TL431

    Resolved
    Part Number: LM5023 Other Parts Discussed in Thread: TL432 , LMV431 , , ATL432 In the schematic diagram,(12V 5A), using the TL432, regulation is suitable up to 12V 2A; after that, the voltage drops significantly. Replacing the TL432 with LMV431, the regulation…

  • RE: LM5022: LM5022 flyback design-loop compensation

    Hi Neo, thanks for the update. So it looks like some disturbance is getting injected on to the FB/REF input of the LMV431 but this should not be a loop stability issue. This issue could be due to: - LMV431 being placed very close or below the…

  • TLV431: TLV431: TLV431 voltage comparator in open-loop configuration issue

    TI Thinks Resolved
    Part Number: TLV431 Other Parts Discussed in Thread: TLVH431 , LMV431 hello everyone, I use the following design from SLVA987A with a TLV431: I have the following issue, this circuit work very well with TLVH431 but not TLV431. When the Vref…
