Maxim Launches Three Power ICs Ideal for IoT Systems
MAX17227A and MAX17291 boost converters,
MAX38911 LDO Extends IoT Battery Life


Maxim Integrated Korea announced on the 16th the launch of three ‘Essential Analog Efficient Power ICs’ to help designers extend battery life and reduce solution size for industrial, consumer, and medical IoT systems.

Next-generation IoT systems are aiming for ultra-small size, low power, and high performance, and the △'MAX17227A' 2A nanoPower boost converter, △'MAX1729' high-voltage 1A boost converter, and △'MAX38911' 500mA LDO support designers in implementing performance without limitations.

The MAX17227A boost converter is ideal for high-power, battery-powered IoT systems, delivering up to 2A of switch current and 350nA of quiescent current. Short-circuit protection, true shutdown circuit, and input voltage range of 400mV to 5.5V extend battery life by up to 10%.

The MAX17291 boost converter delivers high-voltage boost up to 20V, while consuming 80% less quiescent current and being 60% smaller than competing devices. It is ideal for battery-powered systems with high output voltage loads, such as displays and sensors.

The MAX38911 LDO is 50% smaller than competing devices and draws only 19µA of idle current, extending battery life by up to 10%. It also offers 70dB of power-supply rejection ratio (PSRR), preventing power-supply noise from interfering with IoT systems' critical functions, such as precision measurements and communications.
