Hello,
At TPS72029, my customer does not want VBIAS to source the light-load drive current when IN pin is left floating.
They would like TPS72029 drive the load only when Vin is available.
In this case, VBIAS still has to be greater than Vout by 1.4V?
My customer would like Vin=VBIAS=3.3V and Vout=2.9V if possible, though.
Best regards,
K.Hirano
