Dear team,
for the design of the compensation I would need to know the correct value and the tolerance of the "45uA typical" current ramp.
Unfortunately only the combination out of the current ramp and the internal 2k resistor is speced as Vslope 83mV...110mV...137mV.
Further it can be found that the text describes a typical Vslope of 100mV. (45uA*2kOhm= 90mV).
It also can be found that the 83mV...110mV...137mV tolerance range was revised and is higher now - compared originally spec.
This means either the 2kOhm resistor is larger or the 45uA current ramp is actually higher.
I need to know the exact spec of the internal current ramp. What is the typical and what is min/max?
many thanks
Lutz
