New nanoPower Boost Regulator for Wearables and Consumer IoT Designs from Maxim
New MAX17222 features 300nA IQ and 95% peak efficiency, reduces solution size by up to 50%
Maxim have released the MAX17222 nanoPower boost regulator with high efficiency and low quiescent current of only 300nA,
enabling long battery life for wearable and consumer IoT designs. The 0.4V to 5.5V input, 1.8V to 5V output boost regulator with 500mA 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 are ideal for wearable devices which IDC forecasts will experience a
compound annual growth rate (CAGR) of 18.4% in 2020.
Designers of new wearable, health-monitoring, Internet of Things (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.
Maxim’s MAX17222 not only delivers the lowest quiescent current, but also minimizes heat dissipation and shutdown current. In True Shutdown™ mode, the minuscule current draw of 0.5nA virtually stops battery drain to provide the longest battery life and eliminate the need for external disconnect switches. Dramatically reducing solution size compared to other similar products, 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, density-optimized 0.88mm x 1.4mm 6-bump WLP and 2mm x 2mm 6-pin standard µDFN packages. It operates over the -40°C to +85°C temperature range.
“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.
Features of the MAX17222 include:
- Longest Battery Life: Battery drain is significantly reduced during standby and shutdown modes to maximize operating time; 0.4V input (with 0.88V startup input) is compatible with low voltage batteries and supercapacitors
- Smallest Solution Size: Highly integrated boost solution resulting in up to 50% space savings over similar products
- Highest Efficiency: 95% peak efficiency minimizes heat dissipation during active operation
