As visualization of electric power consumption proceeds among houses or any types of buildings, the number of smart meters has been increasing. Those meters are equipped with various kinds of sensors that monitor temperature, voltage, current, etc., and wireless communication ICs. In order to secure the sensing accuracy of those sensors and to achieve stable wireless communication, power management ICs must supply clean, low-noise power to those sensors and communication devices.
Ricoh Electronic Devices has a wide lineup of power management ICs that have low-noise features and contribute to reducing size and supply current of various systems or applications, of course including smart meters.
