Other Parts Discussed in Thread: UCC2895, UCC28950, UCD3138
Dear Sir or Madam, I am currently using UCC3895 for Peak Current Mode control PSFB PWM generator.
I read the datasheet and I set the current sensor value of 0-2V, the frequency 25K, and deadtime about 1us.
The thing is, for advanced control algorithm, I need to pass an analog value from my MCU's DAC to UCC3895 wishing to set the Peak current value directly.
However, I am not sure whether I am using it correctly by connecting the value from MCU to EAP and shorting the EAN and EAOUT.
Another thing is, I see all reference schematic diagram using a transistor at CT, I am not sure whether it was for chopping off the current at peak current and I just copied the part of circuit
from one design. Will my design of transistor work as expected?
Could you help me to check whether there is any other issue of this circuit?
Thank you very much!
