Monolithic Power Systems (MPS) MP5493 Switching Voltage Regulators
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.
