Hi,
I got some questions about UCC28950 as follows.
Could I ask for some advice?
(1)
if not use UCC28950 secondary sync function and Master/slave sync function,
How should I connect these following Pins?
8pin DELEF
12pin DCM (to GND?)
13pin ADELEF (to GND?)
16pin SYNC (open?)
17pin OUTF (Open?)
18pin OUTE (Open?)
(2)
Is there any limitation or ABSOLUTE MAXIMUM RATINGS for COMP pin source/Sink current?
(3)
Regarding the formula for calculating VSLOPE2 voltage,
these 2 formulas are different, which one is correct?
