  • ROHM has recently announced the availability of a DC/DC converter with integrated MOSFET that achieves the lowest current consumption in the industry, making it ideal for compact battery-driven devices including IoT, wearables, and portable equipment.
    The BD70522GUL is an ultra-low-power converter designed to meet the needs of the IoT market to deliver 10-year operation on a single coin battery. Combining its vertically integrated production system that leverages power expertise with proprietary Nano Energy technology developed utilizing industry-leading analog expertise in circuit design, layout, and processes has allowed ROHM to deliver 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 (10uA to 500mA).

Nano_Energy overview

Background

In recent years, the number of battery-driven portable devices such as smartphones, wearables, and IoT has risen dramatically. This increases the demand for smaller components that can provide greater design flexibility along with the necessary space for integrating new features while also achieving lower power consumption to prolong battery life.
