Press Release
Texas Instruments and Wurth Electronics Midcom create suite of
Power-over-Ethernet applications
Wurth Electronics Midcom Inc., a world leader in the design and
manufacture of transformers and custom magnetics, recently designed in
three Power-over-Ethernet (PoE) reference designs with Texas
Instruments.
Featured on the suite of PoE designs from Texas Instruments is a WELAN transformer module and at least one WE-PD4 inductor. The WELAN transformer module provides coupling and impedance matching
from the IC to the Ethernet line and provides exceptionally low crosstalk.
It also has a high level of common mode noise rejection from the
integrated common mode choke and provides low insertion and return
losses. The PoE LAN transformer module comes in a compact, surface
mount design and has an operating temperature from -40°C to 85°C.
Highlighted on the TPS23750-HPA108 is a custom made Wurth
Electronics Midcom flyback transformer (750310040) designed
specifically for Texas Instruments. The flyback transformer comes in a
compact 12 pin, EFD15 SMD design. It has a low leakage inductance of
2.4μH for high efficiency, and a primary inductance of 146μH. The
transformer carries 500VDC isolation and has low DCR on all windings
with an operating temperature of -40°C to 125°C.
The designs: TPS23750-HPA107EVM, TPS23750-HPA108EVM and the
TPS23753AEVM-004, implement IEEE 802.3af-compliant, class-3,
power interface and a DC/DC switching converter using the Texas
Instruments controllers in a typical PoE configuration. The layouts come
in buck and flyback topologies, and the IC contains a complete PoE
interface. The front end of the PoE includes detection, classification, as
well as under voltage lockout and current inrush control. The PoE switch
is included within the IC. Applications include IP telephones, wireless
access points and wired IP cameras.
