Power Losses and Efficiency vs. Output Power for LIGHTING−POWER−POE−GEVB Startup and on Board Minimum Power Signature Generator Since there is no load at the PoE board output and Minimum Power Signature is not generated, PSE shuts off after given time (>310 ms). PSE repeats this sequence in about 3.5 s. NOTE: Phihong POE90U−1BT PSE was used during these tests. No Load Startup with on Board MPS Generator Turned OFF As can be seen in waveforms below, PSE device processes normal startup procedure and provides power afterwards. www.onsemi.com 11 EVBUM2705/D Figure 16. No Load Start−up, MPS Circuit OFF www.onsemi.com 12 EVBUM2705/D No Load Startup with on Board MPS Generator Turned ON afterwards. Since PSE output is now loaded by current pattern conform to Minimum Power Signature given by relevant PoE standard, PSE provides power to PoE board continuously. With on board MPS generator activated, PSE device processes normal startup procedure and provides power Figure 17. No Load Start−up, MPS Circuit Turned ON On Board MPS Generator components (see next slide) in case different pattern is needed. As can be seen in waveforms below, first MPS pulse comes within 187 ms after PSE provides power. All succeeding pulse gaps are 265 ms wide, followed by 70 ms pulses. To keep circuitry small/cheap, simple multi−vibrator has been selected for on board MPS generator. It can be deactivated by applying positive voltage to MPS_EXT pin of output connector or digitally over I2C expander installed on board as well. Generated MPS pattern can be easily altered or completely deactivated modifying relevant RC www.onsemi.com 13 EVBUM2705/D Figure 18.
