I created a custom board to test the ADP5052 buck regulator.
The output voltage for the stages I want is good except for 1 channel which does not correctly work untill the input voltage is more than 5V. If the voltage is lower,ex, 4.8, the output voltage drops linearly under the voltage requried (3V).
I found an equation in the datasheet that talks about this but when I use it, the maximum output voltage is around 4V. I cannot generate 3V unless the input voltage is more than 5V. I am afraid that the system may have 4.8 to 5V input supply.
