  • Forum Post: LM20333, problems with VIN range

    Lucas Loizaga
    Hello! We are working with LM20333, and we are experimenting some problems with the input voltage range. Basically, our design is exactly the same suggested by the webench of national.com (VOUT=5V) and works fine between 9 to 17.5V of VIN, but the VOUT voltage shutdown's when the VIN exceeds 18V...

  • Forum Post: TPS63700 DC output voltage accuracy

    Tim Hoeppner
    Hello, What test conditions are used for "DC output accuracy" under the "ELECTRICAL CHARACTERISTICS" in the TPS63700 datasheet? Does it include feedback resistor tolerance, temp co, reference voltage variation? If so, what tolerance resistors were used? Thank you for any...

    Michael Day
    I do not know the other customer's final resolution. They did not reply with what they did to solve their problem. I would like to recommend that you contact your local FAE in India. They will be able to work directly with you understand the waveforms and help find the problem. Without actually seeing...

  • Forum Post: LM3670 - output accuracy

    Leon Sae-Ung
    Hello, on page 4 we can see the accuracy depending on the output voltage for LM3670. I do not see why for the 3.3Vout we see -6% max whereas for the other output values the accuracy is closer to -4% or -4.5%. Could you please help to understand? Thanks!

  • Forum Post: TPS53355 and differential voltage feedback

    Michael Hershkovich
    Hi, You probably know that some CPUs have an differential voltage feedback pins which supposed to be used with the main power supply module. I'm using the TPS53355DQPT as my main power supply module with maximum output: 1v@24A. This power module don't have dedicated differential voltage...

  • Forum Post: RE: LM2623 Voltage Ripple

    Daniel Kern
    First of all, while Ryan Tuck's comments were a little bit 'snarky', at least they elicited a response. So thanks! I do realize that my original question was vague. I'm not looking for someone to magically find the reason for my excessive voltage ripple. Rather, I'd like it if someone...
