With the lowest quiescent current (Iq) in its class of 6µA, as well as the highest peak efficiency of 96% in the market, designers can now maximize a portable device’s battery life with the MAX77827 buck-boost converter from Maxim Integrated Products, Inc. This 1.5A high-efficiency, compact converter allows 1.8V to 5.5V input and 2.3V to 5.3V output, while providing the system stability needed to minimize abrupt or unexpected shutdowns. The MAX77827 addresses the power requirements of low-power wide-area network (LPWAN) applications, asset tracking devices and many internet of things (IoT) applications.

It is an ideal solution to support applications with low power requirements because, regardless of the battery voltage variations, it can automatically transition between buck and boost modes to provide a consistent output power supply. Compared with utilizing a buck converter, it allows continuous system operation with lower voltage from the battery to further utilize the battery capacity (more info).
