Maxim launches nanoPower range with boost regulator for smallest wearable and consumer IoT designs
The MAX17222 has an input range of 0.4V to 5.5V to a 1.8V to 5V output with 500mA input current limit, and the 0.4V input (with 0.88V startup input) is designed to be compatible with low voltage batteries and supercapacitors. It reduces board footprint by up to 50% compared to similar products and offers 95% peak efficiency to minimize heat dissipation. These benefits are aimed at wearable devices which IDC forecasts will experience a compound annual growth rate (CAGR) of 18.4% in 2020.
Maxim is also launching a full suite of nanoPower solutions, including comparators, op amps, and supervisors targeted for ultra-low power applications.
To get the long battery life, the boost regulator uses a True Shutdown mode with a current draw of 0.5nA provides a long battery life and eliminate 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 design, reducing the footprint. It comes in 0.88mm x 1.4mm 6-Bump WLP and 2mm x 2mm 6-Pin standard µDFN packages and 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.
The MAX17222ELT+ is available for $1.23 and the MAX17222EVKIT# evaluation kit is available for $34.99. An EE-Sim model is also available.
Other products within the nanoPower family will be available in 4-6 weeks with different input/output current levels.
