ROHM Semiconductor has developed a new evaluation board, the BD83070GWL-EVK-002, designed to showcase its BD83070GWL buck-boost DC-DC converter IC. The board achieves an ultra-compact mounting area of 12.87 square millimeters, integrating the IC with a coil, capacitors, and a total of only five components. The BD83070GWL IC itself delivers up to 97% efficiency and an ultra-low quiescent current of 2.8 microamps, targeting small battery-powered devices such as wearables, mobile devices, and IoT products. As a reference design, circuit patterns and the bill of materials are publicly available to ease the transition from evaluation to mass production. The board is now available for purchase through online distributors including DigiKey and Farnell.
