Vin 5v @ 0.12A > Vout 3.3v @ 165mA 0,54W 91%, stable, low ripples, above 7.6Vin=unstable SW.
Vin 5v @ 0.59A > Vout 3.3v @ 700mA 2.31W 78%, stable, low ripples.
Vin 9v @ 0.15A > Vout 5v @ 250mA 1.25W 93%, stable, low ripples. 10Vin=unstable SW.
Vin 9v @ 0.79A > Vout 5v @ 1.06A 5.32W 75%, stable, low ripples.
Vin 12v @ 0.6A > Vout 5v @ 1.06A 5.32W 74%, stable, low ripples, 0.8Vp-p spikes, some jittery switching at various input voltages.
Vin 24v @ 0.66A > Vout 12v @ 1.2A 14.4W 91%, stable, 0.2Vp-p ripples, 1.5Vp-p spikes.
2.0-2.7V output = sometimes unstable switching. Less than 2.0V out = unstable switching. Less than 2.5V in/out voltage = unstable switching.
Small size inductor is good to 1.5A output.

Vin 12v @ 0.4A Vout 5v @ 0.9A efficiency 93.7%
Vin 12v @ 0.9A Vout 5v @ 1.8A efficiency 83.3%
Sweet spot, if Vout = 3.3, then Vin = 5 <> Vin 12, Vout 9..5 @ 1 Amp , so 9W to 5Watts
