描述 Description

The PTB48540 series of power modules

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 connections,

an integral transient suppressor

for input over-voltage protection, and

an EMI filter to ensure noise compatibility

with Ethernet data signals.

Other features include an input undervoltage

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.
