The Maxim Integrated Products MAX17222 nanoPower boost regulator offers a quiescent current (IQ ) of only 300nA and enables the longest battery life in the smallest form factor for wearable and consumer IoT designs. The 0.4 to 5.5-V input (with 0.88-V startup input), 1.8 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 minimize heat dissipation. These benefits suit wearable devices, which IDC forecasts will experience a compound annual growth rate (CAGR) of 18.4% in 2020.
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.
The MAX17222 boost regulator also minimizes heat dissipation and shutdown current. In True Shutdown mode, the 0.5-nA current draw nearly stops battery drain and eliminates the need for external disconnect switches. The device is internally compensated and requires only a single configuration resistor and small output filter for a full power solution. The boost regulator comes in 0.88 x 1.4 mm, 6-Bump WLP and 2 x 2 mm 6-Pin standard µDFN packages. It operates from -40°C to +85°C temperature range.
