    One more set of data I just found to help show the fsw vs Vout is below. Operating near the minimum on-time causes the fsw to start to decrease with the 0.6V output with 12-V input so data at 6-V input is also given.

      Vin = 12 V, Vout = 0.6V, Iout = 5A Vin = 6 V, Vout = 0.6V, Iout = 5A Vin = 12 V, Vout = 1.0V, Iout = 5A Vin = 12V, Vout = 5.5V, Iout = 8A
