SY5040 Datasheet (Silergy) - CCM+QR Mode SSR Flyback Controller

SY5040, CCM+QR Mode SSR Flyback Controller

SY5040 is a peak current mode SSR flyback controller that combine CCM and QR mode together to minimize transformer size and achieve high efficiency.

Under low line and heavy load condition, SY5040 works under CCM, while under high line or medium load, it works under QR mode (valley switching).
