Analog Devices announced the launch of two basic analog high efficiency power IC series nanoPower modules that help designers extend battery life and reduce the size of space-constrained Internet of Things (IoT) devices. The MAXM38643 offers 1.8V to 5.5V inputs, 330nA static current (IQ), and 600mA step-down modules, while the MAXM17225 offers 0.4V to 5.5V inputs, 300nA IQ, and true-off 1A step-up modules, offering lower IQ and longer battery life than competing solutions. By integrating preset inductors, these miniature system-level IC modules (uSLIC™) can speed time to market and reduce the size of the standalone IC plus external inductors solution by 37%. Applications include space-constrained consumer products, wearables, medical drug delivery, sensors, IoT devices, wired, wireless, and industrial products.

     Battery-powered IoT devices require a lower IQ in standby mode to provide longer battery life. In addition, the ultra-low turn-off current (0.5nA for the MAXM17225 and 1nA for the MAXM38643) gives the system virtually zero power consumption during the turn-off mode. The static current of the MAXM38643 and MAXM17225 is an order of magnitude lower (1/10 and 1/20, respectively) than competing solutions with the same output current. In addition, the MAXM38643 and MAXM17225 topped the competition with peak efficiency of 96% and 95%, respectively.

     As a result, these modules consume less power, providing longer life and reducing carbon emissions from battery-powered and long-term online devices. Both products use Analog Devices' uSLIC power module technology to provide stackable, integrated inductors that allow designers to reduce the surface area of the solution PCB and eliminate time spent in component selection and circuit board layout.

     "In addition to extending the battery life of the next generation of micro-iot devices, the nanoPower MAXM38643 step-down and MAXM17225 step-up modules improve the functionality of many sensors, radio and digital circuits in consumer, medical and industrial applications that require lower IQs and higher output currents."
