Analog Devices Launches New Basic Analog nanoPower Module to Extend Battery Life in Space-Constrained Applications

MAXM38643 and MAXM17225 have lower quiescent current than competing solutions; uSLIC internal inductor technology reduces solution size by more than 37%

Beijing, China – December 2, 2021 – Analog Devices, Inc. announced the launch of two basic analog high-efficiency power IC series nanoPower modules with built-in inductors to help designers extend battery life and reduce size in space-constrained Internet of Things (IoT) devices. The MAXM38643 provides a 1.8V to 5.5V input, 330nA quiescent current (IQ), 600mA step-down module, and the MAXM17225 provides a 0.4V to 5.5V input, 300nA IQ, true shutdown 1A boost module, which has lower IQ and longer battery life than competing solutions. By integrating a preset inductor, these micro system-level IC modules (uSLIC™) can speed up time to market and reduce the size of the solution by 37% compared to stand-alone ICs plus external inductors. Applications include space-constrained consumer products, wearable devices, medical drug delivery, sensors, IoT devices, as well as wired, wireless and industrial products.

Battery-powered IoT devices require lower IQ in standby mode to provide longer battery life. In addition, ultra-low shutdown current (0.5nA for MAXM17225 and 1nA for MAXM38643) enables the system to consume almost zero power during shutdown mode. Compared with competing solutions with equivalent output current, the quiescent current of MAXM38643 and MAXM17225 is an order of magnitude lower (1/10 and 1/20, respectively). In addition, the peak efficiency of MAXM38643 and MAXM17225 is 96% and 95%, respectively, which is the best among many competing solutions. As a result, these modules consume less power, providing longer life and reducing the carbon footprint of battery-powered and long-term online devices. Both products use Analog Devices' uSLIC power module technology, providing stacked, integrated inductors, allowing designers to reduce the surface area of ​​the solution PCB and save time on component selection and board layout.

“In addition to extending battery life in next-generation tiny IoT devices, the nanoPower MAXM38643 step-down and MAXM17225 step-up modules improve the functionality of many sensors, radios, and digital circuits in consumer, medical, and industrial applications that require lower IQ and higher output current,” said Chinmay Honrao, business manager for standard power products in the Core Products Group at Analog Devices.

Basic analog ICs have Analog Devices' consistent advantages in low power, high performance, single-function products, and will vigorously promote the next generation of innovation in a variety of applications and market fields.

Features and Benefits of the MAXM38643 Buck Module and the MAXM17225 Boost Module

• Longer Battery Life: Lower static power consumption than competing solutions, helping to extend the battery life of online devices.

• Smaller solution size: Provides stacked, built-in inductor 3D module solution size, which is more than 37% smaller than independent IC solutions

• Shortened design time: No need for inductor selection, design and procurement, shortening time to market
