Monolithic Power Systems (MPS) MP5493 Switching Voltage Regulators provide compact and efficient energy management solutions for the Power Line Carrier (PLC) in power meters. These regulators include a buck DC/DC converter combined with a bidirectional DC/DC converter that supports a supercapacitor charger and boost topology. The MP5493 regulators use a bidirectional converter to achieve optimal energy transfer and to provide the most cost-effective energy storage solution. These switching voltage regulators operate at 5V to 36V input voltage range. The MP5493 regulators are available in the TSOT23-8 package. These regulators are ideal for PLC modules, power meters, backup capacitor systems, and power failure backup systems.
