Datasheet Summary
DESCRIPTION
The MP5493 is an energy backup and management unit that provides a very pact and efficient energy management solution for the power line carrier (PLC) in power meters. The MP5493 consists of a buck DC/DC converter bined 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.
The MP5493 achieves high power conversion efficiency across a wide load range by scaling down the switching frequency (fSW) under lightload conditions to reduce switching and gate driving losses. Thermal shutdown provides...
