  • LM27761EVM: Two possible voltage output.

    Part Number: LM27761EVM Other Parts Discussed in Thread: LM27761 , LM339A According to the data sheet, the formula for Vout is -1.22*(R1+R2)/R2 where Vfb should be (1.22) between 1.202V and 1.238V So I choose R1=115K and R2=499K to get Vout=-1.5V However…

  • RE: LM27761: LM27761DSG failure problem

    Hello user, Thanks for your question and sorry for the late answer. The topic of current limiting resistor on EN pin is strictly dependent on the specific device implementation. Referring to the EVM ( Using the LM27761EVM Evaluation Module ), you can see…

  • RE: LM27761 switching spurs: is there a way to reduce amplitude of the switching spurs

    Hi, Did you replace LDO output capacitor or charge pump output capacitor? If you have not replaced charge pump output capacitor, that is one thing you could try. You might have to also increase value of the flying capacitor. Another thing is DC bias…
