  • 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…

  • LM5008A: efficiency is lower than expected

    Resolved
    Part Number: LM5008A My customer is using LM5008A to generate 5V, load is 800mW, when input is 10V, the input power is 1W, when input voltage is 85V, the input power is 5.5W, which is obviously lower than the efficiency curve in datasheet. Are there any…

  • DRV8350R: Integrated LM5008A buck regulator

    TI Thinks Resolved
    Part Number: DRV8350R Other Parts Discussed in Thread: DRV8350 , LM5009A , LM5008A , LM5008 if the Input voltage on the Vin is above 44V the switching node shows an unexpected behaviour. Can you explain it? DRV8350_TI_Support.docx

  • RE: DRV8353: For dual-supply architecture, any power sequencing requirements?

    Hi Michael, I do have an update: Michael Shonle said: The datasheet doesn't mention whether the Vvdrain pin can be powered if the Vm pin isn't (and vice-versa, though not a situation we'll run into). To be safe and ensure an undervoltage fault…

  • LM5008A: Output power

    TI Thinks Resolved
    Part Number: LM5008A Other Parts Discussed in Thread: DRV8350R , HI, team, My customer will use DRV8350R (which integrates LM5008A) and would like to check if the device can support his output power. The requirement is - Vin : DC 40 ~ 60V - Vout : 700mW…

  • LM5008A: Please help to check is there any risk to damage diode.

    TI Thinks Resolved
    Part Number: LM5008A Hi expert, The attached is our design. But the diode is damage, it is short circuit. This issue happened at our customer's side. Is there any reason to damage the diode? B1100-13-F.pdf LM5008A.pdf

  • LM5008A: LM5008A - non smooth startup

    TI Thinks Resolved
    Part Number: LM5008A Dear E2E, we are suffering non smooth startup issue. We found that it is due to Vin startup too slow because RT/SD pin is tie to Vin through resistor. so, we try to fast up Vin then Vout is more smooth startup. However, there are…
