LвЂ‰DESIGN FEATURES PD Controller ICs with Integrated
Flyback or Forward Controllers Meet
by Ryan Huff
Demands of 25.5W PoE+
Introduction
The IEEE 802.3af Power over Ethernet (PoE) standard allows a powered
device (PD), such as an internet
protocol (IP) telephone, to draw up to
12.95W from an Ethernet cable. When
the 802.3af standard was drafted,
12.95W appeared sufficient to cover
the immediately imaginable range of
PD products (primarily IP phones).
Of course, application developers
are always far more innovative than
standards committees anticipate, so
new power-hungry applications for
PoE immediately started to appear,
such as dual-radio IEEE 802.11a/g
and 802.11n wireless access points,
security cameras with pan/tilt/zoom
motors, and color LCD IP video
phones. 12.95W was suddenly not …
