Analog Devices MAXM38643 and MAXM17225 Essential Analog IC modules

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

The MAXM38643 1.8 to 5.5 V input, 330 nA quiescent current (I_Q), 600 mA buck module and the MAXM17225 0.4 to 5.5 V input, 300 nA I_Q, 1A boost module with True Shutdown are claimed to feature the lowest I_Q compared to competitive solutions and to deliver more battery life. By integrating a preselected inductor, the micro system-level IC (uSLIC) modules are said to accelerate time to market and to be up to 37% smaller in size compared to a standalone IC plus external inductor. Applications include space-constrained consumer products, wearables, medical drug delivery, sensors and IoT devices, as well as wired, wireless and industrial products.

Battery-powered IoT devices require low I_Q in system standby mode to deliver long battery life. Further, ultralow shutdown current (0.5 nA on MAXM17225 and 1 nA on MAXM38643) allows systems to consume virtually no system power during shutdown mode. The MAXM38643 and MAXM17225 consume an order of magnitude less quiescent current (one-10th and one-20th, respectively) than competitive solutions with similar output currents. In addition, they have peak efficiencies of 96% and 95% respectively. 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.

The products utilise Analog Devices’ uSLIC power module technology featuring stacked, integrated inductors that enable designers to reduce solution PCB surface area and eliminate the time spent on component selection and board placement. The modules can also increase functionality for many sensors, radio and digital circuits in consumer, medical and industrial applications which require low I_Q and high output current.
