    IEEE 802.3bt PD Interface
    with Forward/Flyback Controller
    Features Description IEEE 802.3af/at/bt(Draft 2.0) Powered Device (PD) with Forward/Flyback Controller
    n Supports Up to 71 Watt PDs
    n 5-Event Classification Sensing
    n Superior Surge Protection (100V Absolute Maximum)
    n Wide Junction Temperature Range (–40°C to 125°C)
    n >94% End-to-End Efficiency with LT4321 Ideal Bridge
    n External Hot Swap N-Channel MOSFET for Lowest Power Dissipation and Highest System Efficiency
    n No-Opto Flyback Operatio Auxiliary Power Support as Low as 9V
    n Easy Migration of LTPoE++В® PDs to IEEE 802.3bt PDs
    n Pin Compatible with LT4276A/B/C
    n 28-Lead 4mm Г— 5mm QFN Package The LTВ®4295 is an IEEE 802.3af/at/bt(Draft 2.0)-compliant powered device (PD) interface controller with a
    switching regulator controller. The T2P output indicates
    the number of classification events received during IEEE
    802.3bt-compliant mutual identification and negotiation
    of available power. n Applications n n The LT4295 supports both forward and flyback power
    supply topologies. The flyback topology supports No-Opto
    feedback. Auxiliary input voltages can be accurately sensed
    with just a resistor divider connected to the AUX pin.
    The LT4295 utilizes an external, low RDS(on) N-channel
    hot swap MOSFET and supports the LT4320/LT4321 ideal ...
