  • LM5170-Q1: LM5170-Q1 IC failure

    Part Number: LM5170-Q1 We've experienced this LM5170-Q1 IC failure in Buck mode and we don't know why. It seems related to rail voltage supplied to this IC as it's partially damaged. Resistance between Vcc to GND is only a few hundred ohms after this…

  • RE: LM5170-Q1: Can we design 6 phases interleave buck using LM5170-Q1 for Automotive Application

    Hi Santosh, You may start from the LM5170EVM-BIDIR with following changes: 3. Remove D3 4. Adjust R78 to set the output voltage 5.Change R18 to set OVPB threshold higher than 42V. 6. Follow below jumper settings for BUCK mode CV output. Best Regards…

  • LM5170: Current Control without outer loop

    Part Number: LM5170 Hello, in my application I have to source 100 A or less in a resistive load of about 0,1 ohm or less. I need only to regulate the current flowing in the load, the voltage across can vary according to the load. Is just enough apply…

  • LM5170: Current control between HV port and resistive load

    Resolved
    Part Number: LM5170 Hello, I have to design a 50/100 A current source, from a power sypply of 14/18 V. The load is resistive and with that current should not be more than 10/12 V. I'm searching for a controller when I can set the desidered current with…

  • LM5170: SPICE model

    Part Number: LM5170 Other Parts Discussed in Thread: TINA-TI Hi All, I have a question about the Spice model of the LM5170. A customer informed me that the PSpice model below is encrypted and cannot be imported into LTSpice. Do you have unencrypted Spice…

  • LM5170-Q1: Relation among Ripk, Rramp, duty

    TI Thinks Resolved
    Part Number: LM5170-Q1 Could you please give me advice for LM5170-Q1? As attached file, the system shows IPK may affect by the RAMP and duty. But calculator doesn't change Boost/ Buck mode duty cycle when %. RAMP selection is updated. 1. Let me know…
