Maxim's Essential Analog Efficient Power ICs

Maxim Integrated Products has introduced essential analog efficient power ICs, MAX17227A 2A nanoPower boost converter, MAX17291 high voltage 1A boost converter, and MAX38911 500mA LDO to enable designers to extend battery life and reduce solution size of consumer, industrial, healthcare, and IoT systems besides improving the efficiency. These new ICs offer lower quiescent current compared to the competing solutions up in the market.

MAX17227A 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. It delivers the high output power and low quiescent current and handles up to 2A switch current which is twice the closest competitive solution. Besides, it consumes half the quiescent current, at just 350nA.

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

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

Long battery life, reduced size (up to 50 percent smaller than the closest competitive solutions), and high reliability are the key advantages of these three new power ICs. The short-circuit protection and high PSRR help IoT systems overcome disruptions in harsh environments.

MAX17227A is available for $0.86, MAX17291 for $0.74 and MAX38911 is available for $0.67 from the company website. The MAX17227AEVKIT#, MAX17291EVKIT#, and MAX38911EVKIT# evaluation kits are available for $69.99 each. Additionally, EE-Sim models are also available for the MAX17227A and MAX17291.
