Hi Team
could you reply to my questions below about ATL432B's comparator mode operation ?
[1] at Vref = 2.4V applied, I observed Ika = 11 uA.
Ika = 11 uA is flowing because Imin(min cathode current for regulation) = Max 35uA spec ?
[2] I applied 10V for Cathode voltage. if I set Vref = 2.8V, I observed Vout was around 2V.
if I reduce the current flowing into REF pin below 2 uA at Vref = 2.8V fixed, Vout was increased to 10V.
may I know why the current flowing into REF pin can affect ATL432B's comparator mode operation ?
and what is the min current flowing into REF pin for ATL432B's best normal operation for ATL432B's comparator mode ?
[3] I applied 10V for Cathode voltage. if I set Vref = 4V, I observed Vout was around 2V.
at that time, I observed REF pin voltage around 2.6V ~ 2.7V.
may I know why REF pin voltage was around 2.6V ~ 2.7V measured even if I supplied 4V ?
