The BD70522GUL is an ultra-low-power converter designed to meet the demand of the IoT market to deliver 10-year operation on a single coin battery. Proprietary Nano Energy® technology, developed utilizing industry-leading analog expertise in circuit design, layout, and processes, allowed ROHM to provide an unprecedented current consumption of just 180nA (nano→10-9). This makes it possible to increase battery drive time by 1.4x over conventional products at no-load (standby), contributing to longer battery life in electronic devices powered by coin-type batteries (i.e. CR2025). At the same time, power conversion efficiency greater than 90% is achieved over the industry’s widest range, from light to max. loads (10?A to 500mA).
