Up and down voltage converters improve battery operation
The MAX17227A and 17291 are boost converters and the MAX38911 is a low dropout voltage regulator from Maxim Integrated Products Inc.

The MAX17227A 2A nanopower boost converter, the MAX17291 high voltage, 1A boost converter and the MAX38911 500mA LDO all provide the low quiescent current. Designers can now extend battery life and reduce equipment size for consumer, industrial, healthcare and IoT systems with these analog ICs.

The MAX17227A has a quiescent current of 350nA, features short-circuit protection, true shutdown and an input voltage range from 400mV to 5.5V, and it can extend battery system life up to 10 percent.

Delivering a high voltage boost up to 20V, the MAX17291 delivers up to 10X voltage conversion and fits battery-operated systems with higher output voltage loads such as industrial energy hold-up, displays or sensors.

Up to 50 percent smaller than competitive solutions, the MAX38911 500mA LDO for battery-operated IoT systems draws only 19microA during idle mode to extend battery life up to 10 percent.
