Analog Devices makes it possible to extend battery life and reduce size of IoT devices

Designers can now extend battery life and reduce size in space-constrained internet of things (IoT) devices with two nanoPower modules with built-in inductors from Analog Devices. Both products are part of Analog Devices’ Essential Analog family of efficient power ICs.

The MAXM38643 1.8 to 5.5V input, 330nA quiescent current (IQ), 600mA buck module, and the MAXM17225 0.4V to 5.5V input, 300nA IQ, 1A boost module with True Shutdown feature the lowest IQ compared to competitive solutions and deliver more battery life.

By integrating a pre-selected inductor, these micro system-level IC modules (uSLIC) accelerate time to market and are up to 37 percent smaller size compared to a standalone IC plus external inductor.

Applications include space-constrained consumer products, wearables, medical drug delivery, sensors, IoT devices, as well as wired, wireless and industrial products.

Battery-powered IoT devices require low IQ in system standby mode to deliver longer battery life. Further, ultra-low shutdown current (0.5nA on MAXM17225 and 1nA on MAXM38643) allows systems to consume virtually no system power during shutdown mode. Both MAXM38643 and MAXM17225 consume an order of magnitude less quiescent current (one-tenth and one-twentieth, respectively) than competitive solutions with similar output currents.

In addition, the MAXM38643 and MAXM17225 have peak efficiencies of 96 percent and 95 percent, respectively — the highest compared to competitive solutions. As a result, the modules consume less power to deliver longer life and reduced carbon footprint for both battery-operated and wired always-on devices. Both products use Analog Devices’ uSLIC power-module technology featuring stacked, integrated inductors that enable designers to reduce solution PCB surface area, eliminating the time spent on component selection and board placement.

“In addition to extending the battery life of tiny IoT devices for next-generation designs, the nanoPower MAXM38643 buck and MAXM17225 boost modules can also increase functionality for many sensors, radio and digital circuits in consumer, medical, and industrial applications which require lower IQ and higher output current,” said Chinmay Honrao, business manager, Standard Power Products for the Core Products Group at Analog Devices.

Essential Analog ICs deliver Analog Devices’ advances in low-power, high-performance, single-function products to enable next-generation innovation in multiple applications and markets.
