Maxim MAX17222 nanoPower boost regulator

The Maxim MAX17222 nanoPower boost regulator enables long battery life in a small form factor for wearable and consumer IoT designs. The 0.4 to 5.5 V input, 1.8 to 5 V output boost regulator with 500 mA input current limit offers 95% peak efficiency to minimise heat dissipation.

In True Shutdown mode, the minuscule current draw of 0.5 nA virtually stops battery drain to provide long battery life and eliminate the need for external disconnect switches. The product is internally compensated and requires only a single configuration resistor and small output filter for a full power system. For ease of use, the boost regulator comes in tiny, density-optimised 0.88 x 1.4 mm 6-Bump WLP and 2 x 2 mm 6-pin standard uDFN packages. It operates over the -40 to +85°C temperature range.
