LM5170EVM-BIDIR: LM5170EVM-BIDIR Testing related queries

Part Number: LM5170EVM-BIDIR


We need help to achieve following operating conditions. Also referred EVM user guide but not getting expected results.

  1. Mode : Boost mode
  2. Input voltage : 12VDC
  3. Output voltage: 48VDC
  4. Output wattage:  700W

1. Can you please share configuration of EVM for the same? It would be helpful for us to moving forward in minimum time.

2. How much load needs to be applied in order to operate boost converter in CCM for 12 V to 48V boost application?



  • Hi Gunesh,

    The Users Guide of the EVM should list all steps of configuration to achieve the described boost mode.
    Regarding the CCM threshold load, there is no exact value given in the EVM guide, however, the minimum load can be calculated based on Vin, Vout, inductance and switching frequency.
    The get a quick estimation of this value, I recommend using our power stage designer tool:
