Microchip develops PoE to USB-C adapter with 60W output
Exceeding the typical 25W output of USB-C adapters, Microchip’s PD-USB-DP60 is a PoE to USB-C adapter delivering up to 60W. It is, also, claims Microchip, the first IEEE 802.3bt PoE to USB Type-C power and data adapter.
As PoE becomes more prevalent and a more convenient solution to provide power over a standard Ethernet cable, it is the most practical solution to provide both power and data up to 100 meters. The PD-USB-DP60 adapter converts both power and data while offering up to 60W USB output power via an Ethernet cable supported by PoE infrastructure.
It can accept up to 90W of PoE and convert it to 60W output over USB-C that will power most cameras, laptops, tablets and other devices using USB-C for input power. The adapter simplifies installation by reducing dependency on AC infrastructure, explains Microchip, to smash the range limitation of three meters for power delivered over 100 meters.
The PD-USB-DP60 also enhances the remote power management capabilities of the USB-C power device. The remote power reset capability, provided by the PoE source, allows power cycling via web interface or Simple Network Management Protocol (SNMP) to reset the device, rather than having to manually unplug and restart at the location of the equipment.
The PoE to USB-C adapter can connect to a variety of PoE sources; it supports newer IEEE 802.3af/at/bt as well as legacy PoE standards.
Able to convert 90W input to 60W output enables devices requiring higher power charging to make use of PoE that could not have done so before, continued Microchip. The adapter can be paired with the company’s cost-effective, single-port and multi-port (up to 24) PoE injectors/midspans and switches that comply with IEEE 802.3af/at/bt industry standards and provide up to 90W power per port. If a lower power is needed to power the USB-C device, IEEE802.3af (15.4W) or IEEE802.3at (30W) PoE sources can be used.
Microchip also offers ICs that enable the PoE to USB-C adapter, including the PD70xxx family of PoE ICs and the LAN7800 USB-to-Ethernet bridge.
Functionality is enabled by Microchip’s Power Delivery Software Framework (PSF), an open source Power Delivery (PD) stack that runs on the UPD301C PD controller and provides full PD 3.0 capability and customization for Microchip’s PD controllers, microcontrollers and USB hubs.
