Maxim’s new Efficient Power ICs offer industry’s lowest quiescent current

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 2A nanoPower boost converter, the MAX17291 high-voltage, 1A boost converter, and the MAX38911 500mA 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.

“The three new Efficient Power ICs from Maxim’s Essential Analog portfolio offer designers a path to simultaneously improve efficiency and reduce solution size,” said Vickram Vathulya, VP, Core Products Group at Maxim Integrated. “For industrial, consumer and healthcare operations, Maxim sets the bar for extending battery life by offering the lowest quiescent power in each category.”

The new Efficient Power ICs from Maxim’s Essential Analog portfolio help ease these tradeoffs with currently the lowest quiescent current and smallest solution size.

MAX17227A: 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 2A switch current, twice that of the closest competitive solution. And it consumes half the quiescent current, at just 350nA.

This nanoPower boost converter 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.

MAX17291: Delivering a high-voltage boost up to 20V, 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.

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

Advantages
