  • LM2670: LM2670 - Inductor value for Iload less than 1 A

    Resolved
    Part Number: LM2670 I am planning to use LM2670 as a basic switching controller for different loads (from 400 mA to 2.5 A) using the same PCB layout. Of course, I will choice a Catch diode and an output capacitor for the worst case (Vout = 15 V @ Iout…
