Space-saving power modules solution is twice as small as previous models

The MAXM15462 and MAXM17532 step-down DC-DC power modules from Maxim Integrated is now in stock with Mouser. Providing an ultra-small power source to drive new developments in machine learning and artificial intelligence, the micro system-level ICs (µSLIC) deliver the benefits of industry-best switching regulators in a form factor that is over two times smaller than previous power modules. The modules are part of the company's Himalaya series of voltage regulator ICs and power modules, which allow cooler, smaller, and more straightforward power supply solutions. The MAXM15642 module runs over a wide input-voltage range of 4.5V to 42V and produces up to 300mA output current over a programmable output voltage from 0.9V to 5V, while the MAXM17532 module has a moderately different input-voltage range of 4V to 42V, up to 100mA output current, and an alterable output voltage from 0.9V to 5.5V. Both modules include a controller, MOSFETs, inductor, and compensation components in a tiny 2.6mm × 3mm × 1.5mm package. Both also use peak-current-mode control architecture and provide a soft-start option to reduce input inrush current. Suitable for use in harsh electrical, mechanical, and thermal environments, the power modules produce increased energy efficiency, shock and vibration tolerance, high-temperature operation, and EMI compliance. The devices possess an ambient operating temperature range of -40C to 125C and are guarded by hiccup overcurrent protection and overtemperature protection. Perfect for space-constrained applications in small enclosures, the modules deliver a robust solution to support next-generation IIoT sensors, motor encoders, network infrastructure equipment, 4mA to 20mA current-loop powered sensors, and LDO regulator replacement.
