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 Inc. 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 systems must provide higher currents from small batteries to support advanced applications such as drug delivery, sensing, machine learning and artificial intelligence. Device limitations force developers into trade-offs 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 trade-offs with both industry-leading lowest quiescent current and smallest solution size.

MAX17227A: For battery-operated consumer accessories, IoT and medical wearable 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.

MAX17291: 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. Delivering up to 10X voltage conversion, this boost converter fits battery-operated systems with higher output voltage loads such as industrial energy hold-up, displays or sensors.

MAX38911: Up to 50 percent smaller than competitive solutions, the MAX38911 500 mV 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
• High Reliability: Features such as short-circuit protection and high PSRR help IoT systems overcome disruptions in harsh environments
