SY23510 Description
SY23510 is a peak current mode SSR flyback controller that bine CCM and QR mode together to minimize transformer size and achieve high efficiency. Under low line and heavy load condition, SY23510 works under CCM, while under high line or medium load, it works under QR mode (valley switching). SY23510 adopts frequency fold back control when load decreases to achieve high average efficiency.
