MAX17227A and MAX17291 boost converters and the MAX38911 LDO shrink size of battery-operated devices

Designers can now extend battery life and reduce solution size of consumer, industrial, healthcare and IoT systems with three new Essential Analog ICs from Maxim Integrated Products. The MAX17227A 2 A nanoPower boost converter, the MAX17291 high voltage, 1 A boost converter and the MAX38911 500 mA LDO all provide the lowest quiescent current among competitive solutions to improve system efficiency and increase battery life.

Next-generation IoT systems must provide higher currents from small batteries to support advanced features such as machine learning and artificial intelligence. Device limitations force developers into tradeoffs that either constrain functionality, shorten battery life or increase solution size. Three new Efficient Power ICs from Maxim’s Essential Analog portfolio help ease these tradeoffs with both industry-leading lowest quiescent current and smallest solution size.


For battery-operated IoT systems that need to boost power, the MAX17227A delivers the highest output power and the lowest quiescent current. It handles up to 2 A switch current, twice that of the closest competitive solution. And it consumes half the quiescent current, at just 350 nA. This nanoPower boost converter features short-circuit protection, true shutdown and an input voltage range from 400 mV to 5.5 V, and it can extend battery system life up to 10 percent.


Delivering a high voltage boost up to 20 V, the MAX17291 offers a quiescent current that is 80 percent lower and a solution size that is 60 percent smaller than the closest competitive offerings. This boost converter fits battery-operated systems with higher output voltage loads such as displays or sensors.


Up to 50 percent smaller than competitive solutions, the MAX38911 500 mA LDO for battery-operated IoT systems draws only 19 µA during idle mode to extend battery life up to 10 percent. It also has the industry’s best power supply rejection ratio (PSRR) at a level 16 dB better than the closest competitor, thus helping prevent noisy power supplies from interfering with critical functions such as precise measurements and communications.

Key Advantages

  • Longest Battery Life:
    All three ICs are part of Maxim’s Efficient Power portfolio and lead the industry with the lowest quiescent current
  • Smallest Size:
    Up to 50 percent smaller than the closest competitive solutions
