New DC-DC converter offers excellent low current consumption

ROHM is offering a new DC-DC converter with integrated MOSFET that delivers what is claimed to be the lowest current consumption in the industry. This makes it perfect for compact battery-driven devices in applications such as wearables, IoT, and portable equipment. The BD70522GUL is an ultra-low-power converter created to meet the requirements of the IoT market to deliver 10-year service on a single coin battery. Nano Energy technology, developed utilising industry-leading analog expertise in circuit layout, design, and processes, has allowed the company to deliver an unparalleled current consumption of just 180nA (nano?10-9). This enables it to increase battery drive time by 1.4x over standard products when operating without a load (standby), adding to longer battery life in electronic devices powered by coin-type batteries, such as a CR2025. Power conversion efficiency larger than 90% is achieved over the industry's widest range at the same time, from light to max. loads (10µA to 500mA).
