The SY23215 is a combined Power-over-Ethernet (PoE) powered device (PD) interface and primary-side controller optimized specifically for isolated converter designs. The SY23215 supports the IEEE 802.3at and 802.3af standards, 25W powered device (PD). External resistors connected to the SY23215 provide the proper IEEE 802.3 signatures for the detection function and programming of the classification mode.
To achieve higher efficiency and better EMI performance, the SY23215 drives flyback converters in quasi-resonant mode and with adaptive PWM/PFM control.
