Reduced power supply system size by 2.25 times

Maxim Integrated Korea has launched the industry's smallest integrated DC-DC power modules, the 'MAXM17532' and 'MAXM15462'.

Designers can reduce product size and increase efficiency by using Maxim's ultra-small (10-pin 2.6mm x 3.0mm x 1.5mm) system unit integrated circuit (uSLIC) family.

With tremendous advancements in sensing, connectivity, and cloud computing, miniaturization technologies are driving new trends like artificial intelligence and machine learning. Next-generation system designs for industrial Internet of Things (IoT) sensors, defense products, network infrastructure equipment, and medical and consumer devices must be driven by data collection and aggregation. New AI products require more power in smaller spaces without heat generation issues.

Maxim Power Solutions MAXM17532 and MAXM15462 for industrial, healthcare, communications, and consumer markets aim to be the industry's best switching regulators with the small size and simplicity of an LDO (linear regulator).

Maxim's power modules integrate a wide-input synchronous buck regulator, FETs, and compensation circuitry in an ultra-small uSLIC size, reducing power-supply solution size by 2.25x. Using these power modules in space-constrained, small systems helps ensure compliance with mechanical and electromagnetic interference (EMI) standards. Engineers can simplify designs by integrating these ready-to-use power modules into a space similar to a small LDO, rather than using bulky, power-hungry conventional regulators. The solutions measure less than ^15mm2 , are highly reliable, and offer peak efficiency exceeding 90%. .

Designing solutions suitable for compact enclosures in extreme mechanical, electrical, and thermal environments requires addressing challenges such as shock and vibration, EMI, energy efficiency, high-temperature operation, and miniaturization. The uSLIC DC-DC buck regulator module operates over a wide input voltage range of 4 to 42 V and a temperature range of -40°C to +125°C. It supports a wide range of applications with nominal input voltages of 5 V, 12 V, 24 V, and 36 V, providing a secure foundation for demanding applications. It complies with the CISPR 22 (EN 55022) Class B EMC standard and the JESD22-B103/B104/B111 drop, shock, and vibration standards.

“As we add more intelligence to our sensors to increase factory throughput and improve profitability, we need greater energy efficiency and smaller solutions,” said Alexander Bohli, Senior Engineer at sensor manufacturer SICK AG. “Maxim’s Himalaya uSLIC power modules simplify our design with their integrated functionality and small size. This solution enables us to offer sensors in smaller housings.”

“These tiny uSLIC power modules will completely transform our customers’ power supply designs,” said Anil Telikepalli, Senior Director of Business Management at Maxim Integrated. “Building on our Himalaya family of regulators, Maxim has innovated to enable power supply modules in an ultra-small system-level package.”
