ADP1607 datasheet say "0.8V to Vout input voltage range"
But when Vin=Vout, it doesn't work. I think.
In other colum, it need reduce diode or cascode FET voltage , I think.
"To use the ADP1607 in the VOUT = 2.5V portion of your application, you would have to reduce the maximum input voltage to 2.5V through diodes or a cascode FET."
1. Minimum ON time of this device?
I would like estimate min duty.
(Why it doesn't have timing condition?)
2. The condition that Vin = Vout is ok
How comes input voltage range is to Vout?
3. If Vin = Vout is OK , why is it missing that data in Fig17?
Sorry it might be primitive questions.
