Hi
My customer is developing an adapter with the LM5020.
The existing specifications are as follows.
Input AC 20 ~ 34V / Output 13V / 2A
However, the input conditions have been changed as follows.
Change specification
Input AC 20 ~ 34V / Input DC 21.6 ~ 26.4V / Output 13V / 2A
When LOAD is over 1.5A under DC 21.6V input condition
There is a problem that the output voltage drops after the duty is 50% limit.
LM5020MM-1 (Duty 80%) Can ic solve the above problem?
In general, we know that the duty is 50% in the FLYBACK circuit. Is it applicable to 80%?
The difference between -1 and -2 is the duty cycle limit, Slope Compensation, when I look up the datasheet. Anything else?
And can you explain Slope Compensation?
