General Description

The MP5493 is an energy backup and management unit that provides a very compact and efficient energy management solution for the power line carrier (PLC) in power meters.

The MP5493 consists of a buck DC/DC converter combined with a bidirectional DC/DC converter that supports a supercapacitor charger and boost topology.

The MP5493 uses the bidirectional converter to achieve optimal energy transfer and to provide the most costeffective energy storage solution.
