RP604 Buck-Boost DC-DC Converters

Nisshinbo RP604 Buck-Boost DC-DC Converters feature a minimum supply current and high efficiency at low loads. The series operates at a low operating quiescent current (0.3µA), making it ideal for wearable devices, applications for the Internet of Things (IoT), and wireless communications modules requiring a low level of current consumption to extend battery life. The converters provide up to 300mA in buck mode. In boost mode, the output current is less and related to the input voltage level. In order to reduce valuable circuit board space, the RP604 converters require only three external components. These devices are offered in compact WLCSP-20-P2 and DFN(PLP)2730-12 packages for design flexibility.
