  • LM2664: LM2664 design inquiry

    TI Thinks Resolved
    Part Number: LM2664 Hello, My customer designed the LM2664 by referring to the reference circuit in the datasheet, and the EVM design. Therefore, there is no capacitor connected to GND on the V+ pin of LM2664. Recently the customer found the Layout…

  • LM2664: LM2664M6/NOPB

    TI Thinks Resolved
    Part Number: LM2664 Tool/software: Hi Team, I am currently working on a design that incorporates the LM2664M6/NOPB voltage inverter, and I have a query regarding the choice of capacitors for the C+ and C- pins as specified in the datasheet. Due to space…

  • RE: LM2664: Inverter switching noise on Local Oscillator

    Hi Nini, I tried these things with no improvement. Perhaps TI could suggest a way to reduce the pulsed energy in the DC signal which feeds the LM2664, even if it is not entirely eliminated I would like to bring it down by just a few dB. Are there other…
