Ultra-small DC-DC power modules provide higher voltages

Engineers designing into applications in medical, factory automation, communications and consumer markets can now link into four new micro-system-level IC ('uSLIC') modules from Maxim Integrated Products. The MAXM17552, MAXM15064, MAXM17900 and MAXM17903 step-down DC-DC power modules join the company's wide portfolio of Himalaya power solutions, providing the broadest input voltage range (4V to 60V) with the smallest solution sizes. While miniaturisation remains the leaning for an array of system designs, many of these designs also need a broad range of input voltages. The newest Himalaya uSLIC power modules extend the portfolio’s range up to 60V versus the previous maximum of 42V and come in a solution size (2.6mm x 3mm x 1.5mm) claimed to be less than half the size of the closest competitive offering. The modules feature a synchronous wide-input Himalaya buck regulator with built-in FETs, compensation and other functions with an integrated shielded inductor. Having the inductor in the module simplifies the toughest aspect of power supply design, allowing designers to create a robust, reliable power supply in less than a day. “With Maxim’s uSLIC modules we were able to add next-generation features into our K30 Illuminated Touch Button enclosure without increasing its physical size,” said Chuck Dolezalek, sr. director of engineering, Lighting Group, Banner Engineering Corp. electronica 2018, November 13-16, 2018, Hall C4, Stand 440
