ADI has introduced the latest basic analog nanoPower module to extend battery life for space-constrained applications

     Analog Devices, Inc announced the launch of two basic analog efficient power supply IC series nanoPower modules with built-in inductors that help designers extend battery life and reduce size in space-constrained Internet of Things (IoT) devices. The MAXM38643 offers 1.8V to 5.5V input, 330nA static current (IQ), 600mA stepdown modules, and the MAXM17225 offers 0.4V to 5.5V input, 300nA IQ, and true turn-off 1A stepup modules, offering lower IQ and longer battery life than competing solutions. By integrating preset inductors, these miniature system-level IC modules (uSLIC™) can accelerate time-to-market and reduce the size by 37% over the stand-alone IC plus external inductor solution. Applications include space-constrained consumer products, wearables, medical and drug delivery, sensors, IoT devices, and wired, wireless and industrial products.

     Battery-powered IoT devices require lower IQ in standby mode to provide longer battery life. In addition, the ultra-low turn-off current (0.5nA for MAXM17225 and 1nA for MAXM38643) enables the system to consume almost zero power during the turn-off mode. The static current of both MAXM38643 and MAXM17225 is one order of magnitude lower (1/10 and 1/20, respectively) than that of competing schemes with the same output current. In addition, the MAXM38643 and MAXM17225 have a peak efficiency of 96% and 95%, respectively, which ranks first among the competing solutions. As a result, these modules consume less power, thus providing longer life and reducing carbon emissions from battery-powered and long-term online devices. Both models use Analog Devices' uSLIC power module technology and offer stackable, integrated inductors that allow designers to reduce the surface area of their solutions' PCBS, as well as time for component selection and board layout.

     "In addition to extending the battery life of next-generation miniature IoT devices, the nanoPower MAXM38643 step down and MAXM17225 boost modules improve the functionality of many sensors, radio, and digital circuits in consumer, medical, and industrial applications that require lower IQ and higher output currents." Chinmay Honrao, business manager of standard power products at Analog Devices' core products division.

     Fundamental Analog ics, with Analog Devices' consistent strengths in low-power, high-performance, single-function products, will drive next-generation innovation across a variety of applications and market segments.
