Campbell, CA, February 7, 2018 – Ricoh Electronic Devices Co., Ltd. has launched the RP604 Buck-Boost DC/DC Converter, designed to use in wearable devices, applications for Internet of Things (IoT) and wireless communications modules requiring a low level of current consumption to extend battery life. In order to reduce valuable circuit board space, the product requires only three external components and has an option to select from two packages.
The RP604 is particularly well suited when a supply voltage is required and located somewhere in between the voltage level of a fully charged and fully discharged battery. At the correct moment the DC/DC Converter switches over from Buck to Boost mode automatically in order to maintain the output voltage setting. The RP604 is designed for applications that are mainly in sleep mode and wake-up periodically to perform a measurement, transmit data and then return to sleep mode. For these type of applications, the current consumption in sleep mode should remain as low as possible. The RP604 has an impressive low quiescent current and consumes only 300 nA, prolonging battery life or makes it possible for the designer to select a smaller sized battery for the application.
