TPE15017 is a monolithic power over ethernet (PoE) powered device (PD) with an integrated PD interface and a flyback power converter.
To achieve a smaller size and high-switching frequency, the TPE15017 fly-back converter is specifically designed with active clamp primary-side regulation (PSR) fly-back topology. TPE15017 can also be set in secondary side regulation (SSR) active clamped fly-back topology, which can get the best regulation through an optocoupler from the secondary side.
