The Analog Devices MAX1722x series can best be described as a low power quiescent current boost DC/DC converter that consumes less than 1µA. It comes in a smaller solution size than previous versions and offers a high efficiency of up to 95%. The True Shutdown™ feature disconnects the input from the output which saves precious battery life.  Some of the key features of this product are the 400mV to 5.5V input range with a 1.8V to 5V output range and 300nA quiescent current. Other key benefits of using this product are the battery life that is 2x longer, with a 50% smaller package size, and rapid heat dissipation.
