peak current mode control

[김남제]

im trying to implement peak current mode contorl using stm32G474 

i have a question about PCMC. in PCMC, if the sensed voltage from Current trasnformer does not reach to target value, does the switch remain  continuously on, or does it turn off according to the original switching frequency?

 

if neither is the case, does it turn off for a very short moment that matches the switching frequency and then turn on again to chasing target voltage? (==> duty ratio nearly 0.99)

 

thank you for infomation
