  • TPS61022: Device get ruined, when used in connection with LM2662

    TI Thinks Resolved
    Part Number: TPS61022 Other Parts Discussed in Thread: LM2662 , , LM2622 Hello, I try to boost form an input of 1.5-2.5V (EDLC) to 10V in a two step prozess. First step is to stup-up to 5V with TPS61022 and then doubling voltage with LM2662. The overall…

  • LM2662: Ceramic or Polymer capacitor for best low ESR/ESL filtering

    TI Thinks Resolved
    Part Number: LM2662 To obtain the lowest ripple noise, is it better to use a ceramic MLCC capacitor or polymer capacitor ? Ceramics are generally recommended for their low ESR but I see polymers available with 5 mOhm at 100 kHz. Polymers are available…

  • LM2662: 5V to 10V

    Resolved
    Part Number: LM2662 Hi! My circuit is according to p.16 of the LM2662 datasheet (voltage doubler), but works as a simple diode, though the oscillator works well. i tried to exchange the IC and switched the load off. There is no difference, the same result…

  • LM2662: 5V to +10V, and -10V 50mA

    TI Thinks Resolved
    Part Number: LM2662 Dear all. Do you have example circuit of folloing spec. Input=5V Output=-10V/50mA and Input=5V Output=10V/50mA Regards, Watanabe

  • RE: LM2660: LM2660M as a replacement for the LM2660MX

    Hello Conor, So you have an input voltage of 2V, right? And with the increased input resistance of LM2660 compared to LM2662 the output voltage is lower because more voltage is dropped through the internal resistors. (If you check the voltage across the…

  • LM2662: minimum Vin for a voltage doubler?

    Resolved
    Part Number: LM2662 The datasheet has a circuit diagram for a voltage doubler that indicates the minimum input voltage is 2.5v while for an inverter it's 1.5v. I am trying to increase the voltage of two LiMH batteries in series: 2.4v. I need an output…

  • LM2662: Paralleling devices when configured as positive voltage doubler

    Part Number: LM2662 Hi, In the LM2662 datasheet, pp. 13, negative voltage converter section, it has been demonstrated to reduce the output resistance by paralleling multiple LM2662 together. I was wondering if I could do the same when the device is configured…
