Maxim Introduces nanoPower Boost Regulator with Industry’s Longest Battery Life for Wearable and Consumer IoT Designs

The MAX17222 nanoPower boost regulator from Maxim Integrated Products, Inc. carries industry’s highest efficiency and lowest quiescent current of only 300nA. With this, the regulator delivers the longest battery life in the smallest form factor for wearable and consumer IoT designs.

Moving on, the booster’s 0.4V to 5.5V input and 1.8V to 5V output with 500mA input current limit reduces the solution size by upto 50% as compared to other similar products. Besides, it offers 95% peak efficiency to minimize heat dissipation. Such benefits are ideal for wearables, which as per IDC forecasts, are going to witness a compound annual growth rate of 18.4% in the year 2020.

Interestingly, the designers of connected devices including wearable, health-monitoring, IoT, and mobile, are struggling in extending battery life for next generation products while increasing functionality and performance in small factors. These power solutions demand expertise in low quiescent current design techniques with high integration.

The MAX17222 not only offers the lowest quiescent current but also minimises shutdown current and heat dissipation. In True Shutdown mode, the minuscule current draw of 0.5nA virtually puts an end to battery drain and removes the need for external disconnect switches.

In addition, Maxim’s regulator dramatically reduces the solution size as compared to other similar products. It’s internally compensated and needs only a single configuration resistor alongside a small output filter for a full power solution.

“Low quiescent current, combined with True Shutdown and high efficiency, helps our customers deliver smart, connected products while meeting demands for high uptime per charge,” said Meng He, Executive Business Manager, Maxim Integrated.

For convenience in use, the boost regulator is offered in tiny, density-optimised 0.88mm x 1.4mm 6-Bump WLP and 2mm x 2mm 6-Pin standard uDFN packages. It works over the temperature range of -40 degree Celsius to +85 degree Celsius.

Product Availability and Pricing

The MAX17222ELT+ can be availed from the Maxim website and select franchises distributors for $1.23, while the MAX17222EVKIT# evaluation kit is offered at $34.99.
