Leveraging Maxim Integrated's patented coupled inductor current ripple cancellation, this AI multiphase chipset delivers a 1% efficiency improvement over competing solutions, enabling over 95% efficiency at 1.8V output and 200A load conditions. This efficiency increase translates to a 16% reduction in wasted energy. It also allows for 40% less output capacitance compared to competing solutions, reducing the overall size of the solution and the number of capacitors. The chipset offers a scalable solution for diverse output current requirements and is customizable to support multiple form factors. Furthermore, the chipset enables AI computing at the edge as well as cloud computing in the data center.

Designers of hyperscale data centers must contend with increased peak power and correspondingly higher thermal levels as they ramp up computing power to meet the growing demands of AI and deep learning applications. AI systems implemented with the MAX16602 and MAX20790 generate less heat compared to competing solutions. Thanks to Maxim Integrated's patented coupled inductor technology and the double-sided, monolithic integrated circuits of the cooling power stage, power loss is reduced as a result of a 50 percent lower switching frequency. The integrated monolithic approach virtually eliminates parasitic resistance and inductance between the FETs and drivers to achieve industry-leading efficiency.

Space constraints also pose a challenge for designers seeking to enhance AI functionality. This chipset enables the smallest overall solution size, allowing developers to reduce the number of components and lower bill of materials (BOM) costs. Furthermore, Maxim Integrated's low-profile coupled inductor technology supports higher saturation current per phase compared to the discrete inductors offered by competing solutions. This allows designers to overcome space limitations by using fewer phases than competitors, while simultaneously reducing the total cost of ownership.
