PoE power devices (PD)

Thanks to technological advances and the newly introduced IEEE 802.3bt standard, the overall power available via Power over Ethernet for powered devices (PD) increases to up to 100W depending on the cable length. Though this development is positive and allows new applications to be powered via PoE, it also introduces new challenges for the DC-DC main power supply of PDs.

• Higher output power, requiring also a point of load (POL) designs depending on the powered device
• Easy to integrate auxiliary power supply to increase flexibility if power is not available or not desired via PoE
• High efficiency to maximize the available power for the PD
• High reliability to avoid failure, even in rough environmental conditions

To meet these demands of DC-DC power supply designs for PoE powered devices, Infineon provides a wide selection of reliable and efficient high voltage and low voltage MOSFETs. Our packaging solutions, e.g. ThinPAK 5x6, enable full automation in your production line facilitating large volume production. We cover a broad portfolio of DC-DC converter solutions such as power management ICs (PMICs) or switching regulators as well as OptiMOS™ low voltage MOSFETs, CoolMOS™ high voltage MOSFETS and our CoolSET™ auxiliary converter systems for AC-DC auxiliary power supplies.

Our team of experts is happy to support you in your design challenges.
