  • RE: LM5180-Q1: Inquiry on operating characteristics at low power

    Resolved
    Hi Junhee, Both EVMs of LM5180-Q1 (see link below) are designed for a Vin_min=10V.What you can do is to order an EVM at ti.com (same links below) and evaluate the performance at VIN=10V (close to 9V). To run power at 5V and 9V, you will need to increase…
