Part Number: UCC28063 Other Parts Discussed in Thread: UCC28061 Dear Expert
Ctm change UCC28063 to UCC28061 ,and system fails to start .The Pin5 COMP is low lever ,other pin voltage are normal.
Below is schemetic ,pls check! 24v8a.pdf
Please tell me the details of the operation of the hysteresis control mode.
(Relationship between COMP voltage and GDA and GDB operation)
The answer is that GDA or GDB may operate independently in the hysteresis control mode, but is it determined by the…
