These modules PTB48540AAZ 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 PTB48540AAZ 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 PTB48540AAZ 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 of PTB48540AAZ 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.
