Code Description Pkg Ref. (1) AH Horiz. T/H (EUP) AS SMD, Standard (2) (EUQ) Output Voltage (PTB48540❒xx) Code Voltage A5 V B 3.3 V C 12 V Notes: (1) Reference the applicable package reference drawing for the dimensions and PC board layout (2) “Standard” option specifies 63/37, Sn/Pb pin solder material. Pin Descriptions –VOUT: This is the negative output from the module, with respect to +Vout. Both the +Vout and –Vout terminals are isolated from the Ethernet input, and used to power the PD appliance. When this pin is connected to the PD appli- ance common, a positive supply voltage is produced at +Vout. VOUT Adj: By connecting a single resistor to this pin, the regulated output voltage may be adjusted/trimmed by up to ±10 % from the original set-point value. If no adjust- ment is desired, this pin should be left open circuit. OUT: This is the positive output from the module with respect to –Vout, and is used to power the PD appliance. By connecting this pin to the PD appliance common, a negative supply voltage will be produced at –Vout. Input Ref: This pin pr ovides access to the –Vin of the internal DC/DC converter, and is the 0-VDC reference for the ‘Output Inhibit’ control. Detect A: This is a control input that is normally left open circuit. The module incorporates an internal 24.9-k Ω resistor, between the ‘ Detect A’ and ‘ Detect B’ pins. This provides the PD with a correct “valid device” detection resistance for the PSE. By placing an external resistor between the ‘Detect A’ and ‘ Detect B’ pins (in parallel with the internal 24.9-kΩ resistor) the module can be made to identify itself as a “non-valid device.” Detect B: This pin is used in conjunction with the ‘Detect A’ input only when it is desired for the PD to communicate a “non-valid” device signature to the PSE (see ‘ Detect A’ description). ‘Detect B’ is also the rectified DC output from the module’s internal diode bridges, and represents the positive DC input to the module’s DC/DC converter. Connecting an external capacitor between this pin and the ‘Input Ref’ pin (0 V), adds more filter capacitance across the input of the DC/DC converter. Data Line A/B: These are the main inputs from which the module obtains DC input power from the Ethernet connector. The connection of these inputs to the Ethernet connections must be via an IEEE 802.3af compliant signal tranformer, that is designed for use in a PoE application. This is necessary to preserve the integrity of the Ethernet data traffic. Consult the example application for further information. Spare Line A/B: These are alternative inputs from which the module may obtain DC input power. In a PoE appli- cation, ‘Spare Line A’ may be directly connected to pins 4 & 5, and ‘Spare Line B’ to pins 7 & 8 of an Ethernet RJ-45 connector. These connections are not used for data trans- mission. Class A/B: The control inputs ‘ Class A’ and ‘Class B’ allow the PD Class to be programmed from the module. The module incorporates an internal 4.42-kΩ resistor between the ‘ Class A ’ and ‘ Class B’ inputs. This corresponds to a default “Class 0” PD classification signature being sent to the PSE. By adding an external resistor across these pins, the module can be programmed to other PD classifications. For further information, consult the PD class reference table in the application notes. Output Inhibit: This is an open-collector (or open-drain) negative logic input. Applying a low-level voltage to this input, with respect to the ‘Input Ref’ pin, turns off the DC output voltage from the module. If the pin is left open-circuit, the module will operate as normal, pro- ducing an output voltage whenever it is connected to a valid PoE input source.

Input power to the module can be supplied through either the Data Line A/B or Spare Line A/B associated Ethernet connections. A diode bridge associated with each of these input pairs allows the input source to be supplied in ei- ther polarity. A transient suppressor, located across the common output of the diode bridges, protects the module against power surges. The input power to the internal DC/DC converter is controlled by the TPS2375 IC. This IC is a power inter- face switch, specifically designed for use with PoE powered devices. The IC provides the device detection, classification, and current limiting control that is necessary for a powered device (PD) to comply with the IEEE 802.af Standard. The DC/DC converter input circuit includes an EMI filter, which maintains the module in compliance with CISPR 22 (EN5022); class ‘B’ for radiated, and class ‘A’ for conducted emissions.

4.42 k (Class 0) PD Detect 24.9 k (Valid Device) –VOUT External RDETECT External RCLASS Input EMI Filter Output Inhibit Figure 1 1; Block Diagram of the PTB48540 Series Modules PD Detection Prior to power up, the PoE power sourcing equipment (PSE) must detect a 24.9-k Ω “discovery” load resistance from the PD. This default value of resistance is neces- sary for the PD to be recognized as a “valid device” by the PSE. A 24.9-k Ω resistor is provided internally to the PTB48540 modules. It is located across the ‘Detect A ’ (pin 5) and ‘Detect B’ (pin 6) terminals. By placing an external resistor across these pins (in parallel with the internal 24.9-kΩ resistor), the module can be made to communicate a “non-valid device” signature to the PSE. A non-valid device is recognized by a resistance of less than 12 kΩ . Connecting a 16.9-k Ω external resistor between the ‘Detect A ’ and ‘Detect B’ pins creates an equivalent resistance of 10 k Ω . This is sufficient to communicate a non-valid device signature. The external resistor should not be less than 16.9 k Ω as this increases power dissipa- tion in the power interface IC. PD Classification Signature The PSE uses a classification current to determine the maximum supply current that the PD is allowed to draw. The classification current is sensed by the PSE when the supply voltage to the PD is between 15 V and 20 V . The classification current is set on the PTB48540 by a pro- gramming resistance.

The power modules support the PD classification protocol with a default ‘Class 0’ signature. ‘Class 0’ corresponds to a 4.42-kΩ programming resis- tance, which is set by an internal resistor located between the ‘Class A’ (pin 12) and ‘Class B’ (pin 11) terminals. By placing an external resistor across the C lass A/B pins (in parallel with the internal 4.42-k Ω resistor) the power module can be made to communicate one of the alternate classifications to the PSE. Consult T able 1-1 for the external resistance values. Under-Voltage Lockout The UVLO prevents the internal DC/DC converter from seeing an input voltage until the voltage applied to either the ‘Data Line A/B’ or ‘Spare Line A/B’ pair of Ethernet connections approaches 42 V . The UVLO threshold correlates to a voltage between the ‘Detect B’ (pin 6) and ‘Class B’ (pin 11) terminals of approximately 39.3 V . Only after the voltage applied from the Ethernet is above the UVLO threshold is the module’s internal bus voltage allowed to rise. The internal bus powers the DC/DC converter and can be measured between the ‘Detect B’ (pin 6) and ‘Input Ref’ (pin 4) terminals. Input Capacitance In accordance with the IEEE 802.3af Standard, the PTB48540 power modules provide an input capacitance of 0.1 µF to the PSE when communicating the required detection and cla ssification signatures. Once fully pow- ered (V in ≥42 V), the PSE will see the combined input capacitance of the EMI filter and DC/DC converter; approximately 7 µF. This capacitance is sufficient to operate the module’ s internal DC/DC converter, and satisfies the 5 µF minimum capacitance required by the IEEE 802.3af Standard. For improved hold-up capability, this input capacitance can be increased with an external capacitor. Connect the anode of the external capacitor to ‘Detect B’ (pin 6), and the cathode to the ‘Input Ref’ (pin 4). During power up the power interface IC limits the inrush current for charging the input capacitance. Additional capacitance increases the power dissipation in the IC. For this reason the maximum recommended value of external capacitance is 220 µF (100-V electrolytic). Startup Startup of the module in a PoE application consists of a complex process of handshaking states between the module and PSE. During the PD detection state the PSE uses a low voltage (<10 V) to detect the module’s “valid device” resistance signature. This is followed by the classification detection state where the PSE applies a voltage of 15 V to 20 V to detect the module’s PD class. The PSE con- tinues to raise the input voltage, but the input voltage to the internal DC/DC converter is held at zero until the voltage from the PSE approaches 42 V . At an input voltage of 42 V or higher, the module’s power interface IC allows the internal bus voltage to rise using a limited amount of inrush current. Approximately 50 ms after the DC/DC converter input filter capacitors are fully charged, the module is able to produce a regulated output voltage. Converter Over-Current Protection The internal DC/DC converter has inherent protection against an output load fault. Whenever its load current exceeds the over-current protection threshold (see speci- fication table) the c onverter momentarily turns its output off. After a short period (<100 ms), the regulator will attempt to power up again by executing a soft-start power up. The converter will continue in a successive cycle of shutdown, followed by soft-start power up until the load fault is removed. When the DC/DC converter is powered from just the Ethernet source, a load current above its rated output (but below its over-current threshold) will likely activate the over-current protection offered by the power interface IC. This is especially at input voltages lower than 48 V . Ethernet Over-Current Protection Protection is also provided for the Ethernet power source equipment (PSE). In event of a fault across the module’s internal bus, the onboard power interface IC limits the maximum current that may be drawn from the PSE to no less than 405 mA. This prevents the DC/DC con- verter from drawing excessive input current and also safeguards against external faults that may occur across the ‘Detect B’ (pin 6) and ‘Input Ref’ (pin 4) terminals. Note: These terminals can be used to add capacitance to the module’s internal bus. Load faults applied to the DC/DC converter’s output will most often trigger the power interface IC’s protec- tion mechanism prior to activating the converter’s own current limit threshold. In these instances the power interface IC will completely shut down the module’ s inter- nal bus. This is a latched condition. It is reset by the PoE source when it attempts another power-up cycle after it senses loss of the PD’s Maintain Power Signature (10 mA). PTB48540 Series Not Recommended for New Designs

This is accomplished with the addition of a single exter- nal resistor. For the input voltage range specified in the data sheet, T able 2-1 gives the allowable adjustment range for each model as V o (min) and V o (max). Adjust Up: An increase in the output voltage is obtained by adding a resistor, R 2 between pin 2 (V out Adj), and pin 1 (–Vout). Adjust Down: Add a resistor (R1), between pin 2 (Vout Adj) and pin 3 (+Vout). Refer to Figure 2-1 and T able 2-2 for both the placement and value of the required resistor, (R 1) or R2. The values of (R1) [adjust down], and R 2 [adjust up], can also be calculated using the following formulas. (R1) = 56.2 (V a – 1.225) – Rs kΩ Vo – Va R2 = 68.845 – Rs kΩ Va – Vo Where, V o = Original output voltage Va = Adjusted output voltage Rs = Internal resistance (T able 2-1) Notes: 1. Use only a single 1 % resistor in either the (R1) or R 2 location. Place the resistor as close to the module as possible. 2. Never connect capacitors to V o adjust. Any capacitance added to the Vo adjust control pin will affect the stability of the module. 3. The output power is limited to 10 W. If the output voltage is increased, the maximum load current must be derated according to the following equation. Io(max) = 10 V a In any instance, the load current must not exceed the converter’ s rated current (See T able 2-1).

The connector J1 is the input from the PoE source. In a Power-over-Ethernet (PoE) application, the power and high-frequency data signals share the same conductors in the Ethernet cable. The data and power signals must be separated using an IEEE 802.3af compliant PoE mag- netic module. The magnetic module incorporates the customary isola- tion transformers, T1 and T2. The transformers each include a center tap, across which the dc current from the Ethernet power source equipment (PSE) is conveniently extracted. The transmit and receive hf Ethernet data appear as differential signals to each transformer. These signals are isolated by the transformers, allowing the Ethernet communication content to flow freely between the connector and the powered device (PD) circuitry. The common-mode inductor, L1, is a popular addition to off-the-shelf PoE magnetic modules. The inductor provides additional rejection to common mode noise currents, which may otherwise be present on either the data or power signals. The PTB48540 module complies with the PoE protocols, provides the required isolation, and converts the raw power from the PSE to a precision regulated 3.3-VDC power source for the remote PD circuitry.
