Low-power boost regulator

15 November 2017 Electronics Technology

With extremely high efficiency and quiescent current of only 300 nA, the MAX17222 nanoPower boost regulator from Maxim Integrated Products enables the longest battery life in the smallest form factor for wearable and consumer IoT designs. The 0,4 V to 5,5 V input, 1,8 V to 5 V output boost regulator with 500 mA input current limit reduces solution size by up to 50% compared to similar products and offers 95% peak efficiency to minimise heat dissipation.

Designers of new wearable, health-monitoring, IoT, mobile, and other connected devices are struggling to extend battery life for next-generation products, particularly with increasing functionality and performance in smaller form factors. Power solutions servicing this market require mastery of low quiescent current design techniques and high integration.

In ‘True Shutdown’ mode, the minuscule current draw of 0,5 nA virtually stops battery drain to provide the longest battery life and eliminate the need for external disconnect switches. Dramatically reducing solution size, the MAX17222 is internally compensated and requires only a single configuration resistor and small output filter for a full power solution.

For ease of use, the boost regulator comes in tiny 0,88 x 1,4 mm 6-bump WLP and 2 x 2 mm 6-pin standard μDFN packages. It operates over the -40°C to +85°C temperature range.
