Description
The PTB48540 series of power mod-
ules is specifically designed to provide
an isolated, low-voltage power source to
a remote Powered Device (PD) in Power-
Over-Ethernet (PoE) applications. These
modules are rated 10 W and incorporate
all the necessary interface requirements
to comply with IEEE Std. 802.3af, for
managing the input power to the PD from
the PoE Power Sourcing Equipment
(PSE). This includes PD detection and
PD classification current signatures
required for the PSE. The modules are
compatible with PD classifications, class 0
through class 3.
In addition to a fully integrated DC/DC
converter, each PTB48540 power module
incorporates internal input diode bridges
to support both Data Line and Spare Line
pair standard Ethernet power connec-
tions, an integral transient suppressor
for input over-voltage protection, and
an EMI filter to ensure noise compat-
ibility with Ethernet data signals.
Other features include an input under-
voltage lockout (UVLO), over-current
and short-circuit protection, an output
voltage adjust/trim, and over-temperature
protection. An “Output Inhibit” control
allows the output voltage to be turned
off to support an idle condition or power
saving mode. The output voltage options
are for 3.3-V, 5-V, or 12-V output. The
target applications are small low-power
remote IP appliances, such as security card
readers and cameras, test dongles, and IP
phone consoles.
