Analog Devices, Inc. (ADI) has introduced two new nanoPower modules with built-in inductors that help extend battery life in space-constrained applications while reducing solution size. The MAXM38643 1.8-V to 5.5-V input, 330-nA quiescent current (IQ), 600-mA buck module and the MAXM17225 0.4-V to 5.5-V input, 300-nA IQ, 1-A boost module with True Shutdown also claim the lowest IQ compared to competitive solutions. Both products are part of Analog Devices’ Essential Analog family of efficient power ICs.

By integrating a preselected inductor, these micro system-level IC modules (uSLIC) are up to 37 percent smaller compared to a standalone IC plus external inductor and accelerate time to market by eliminating the inductor selection and sourcing, said ADI. (The uSLIC power module technology features stacked, integrated inductors.) Applications include 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, said ADI, and both the MAXM38643 and MAXM17225 consume an order of magnitude less quiescent current (one-tenth and one-twentieth, respectively) than competitive solutions with similar output currents.
The MAXM38643 and MAXM17225 also feature peak efficiencies of 96 percent and 95 percent respectively, reportedly, the highest compared to competitive solutions. This translates into lower power consumption for longer life and reduced carbon footprint for both battery-operated and wired always-on devices.

In addition, the ultra-low shutdown current (0.5 nA for the MAXM17225 and 1 nA for the MAXM38643) allows systems to consume virtually no system power during shutdown mode, said ADI.

Available now, the MAXM38643 and the MAXM17225 devices, both housed in 2.1 × 2.6-mm, EMGA-10-pin packages, are priced at $1.22 per 1,000 units and $1.27 per 1,000 units, respectively. An evaluation kit for the MAXM38643 (MAXM38643AEVK#EMGA) and the MAXM17225 (MAXM17225EVK#EMGA) are also available now. They are priced at $62.32 each.
Other devices added to the Essential Analog IC family this year include the MAX17227A 2 A nanoPower boost converter, the MAX17291 high voltage, 1 A boost converter, and the MAX38911 500 mA LDO and the MAX41400 instrumentation amplifier, MAX40108 precision operational amplifier, and MAX31343 real-time clock (RTC) with integrated MEMS oscillator.
