PMP7146.1, 3-ph E-Meter. Input voltage: 2 and 3 phase, outputs: 16.5V@300mApk,12V@500mA,3.3V@100mApk,1.9V@150mA. PMP7146 has been designed especially for E-meters with PLC (power line communication) on board. input filter shows high impedance to PLC transmitter and controller LM5021 works in constant switching frequency. A settable skip-mode improves efficiency at light load. Two Bucks and an LDO supply power to digital section of E-meter
