  • LM5008A: Always voltage on the output (0,6V)

    Part Number: LM5008A Hi, I'm using the LM5008AMM in a battery. It provides 3.3V for MCU. When turned on, everything is working correctly. 3.3V are provided. My problem is: When turning it off, there is always 0.65V on the output. And therefore we have…

  • LM5008A: Bad voltage regulation and high switching noise

    Part Number: LM5008A Other Parts Discussed in Thread: LM5008 We are using a LM5008A circuit to step down 48V to 12V in our design. That 12V is then used by two linear regulators (UA78M05, UA78M33) to generate our 3.3V and 5V rails. We are running into…

  • LM5008A: NOPB Switch Node Question

    TI Thinks Resolved
    Part Number: LM5008A Dear team Customer have some question, could you give some recommend? We found the following problems when measuring Switch nodes. As shown in the attachment, glitch will occur under full load, but no glitch occurs under light load…

  • LM5008A: Component blows up (from dv/dt?)

    Resolved
    Part Number: LM5008A Other Parts Discussed in Thread: LM5008 Hi WIthout pre-charge before connecting, the component blows up above above a certain input voltage (the input pin burns up, and/or top cover burns up close to input pin). Output voltage instantly…

  • RE: LM5008A: Device not starting up

    Resolved
    Hi Ankit, We have used the QuickStart Calculator as you suggested, and almost all the components is within the recommended values. The biggest difference is with the inductor, where we use 270uH and the calculator suggest a minimum of 666uH. With the…

  • LM5008A: LM5008ASDX/NOPB

    TI Thinks Resolved
    Part Number: LM5008A I used LM5008A designed a circuit ,used a application of TI MD015A's example to convert 24v to 12v,but my inductor is hot soon ,i don't know why ,how can i correct this design?

  • LM5008A: No Vout and VCC

    Part Number: LM5008A Hello, Can you please help advise what else we can check on LM5008A? It has no VOUT and VCC. We've checked the RT/SD pin and the voltage is approximately 23.5 V，and VIN is approximate 24.2V. We've tried with another chip, but it…

  • LM5008A: About Minimum Time off in COT

    TI Thinks Resolved
    Part Number: LM5008A Hello, I'm looking the LM5008A datasheet, and I could find the value of "Minimum Time off" which is 300ns. I do not understand what it is even I read whole datasheet. COT is working when Vfb goes lower than Vref, switch…
