Description

The PMP7146 has been designed especially for E-meters with PLC (power line communication) on board. The input filter shows high impedance to the PLC transmitter and the controller LM5021 works in constant switching frequency. A settable skip-mode improves the efficiency at light load. Two Bucks and an LDO supply the power to the digital section of the E-meter.
