New buck-boost DC-DC converter delivers power savings

ROHM offers a buck-boost DC-DC converter with integrated MOSFET, the BD83070GWL. It unites superb efficiency with excellent current consumption, making it ideal for wearables, IoT, and portable devices.

The BD83070GWL was created to be the best-in-class product for low power eco-friendly devices employed in compact battery-driven applications. The built-in low-RDS(on) MOSFET and low control current circuitry achieve an industry-leading power conversion efficiency of 97% throughout operation (@200mA load current) along with class-leading 2.8μA quiescent current consumption. This contributes to longer operating time in compact battery-driven devices, prolonging battery life by as much as 1.53 times in comparison to other conventional products throughout standby (100μA load current). An evaluation board integrating this converter is also available.
