It started with a vision. Michael Hsing, pioneering engineer and CEO, founded Monolithic Power Systems, Inc. (MPS) in 1997 with the belief that an entire power system could be integrated onto a single chip, which would greatly enhance system performance and eliminate most of the iterative design efforts. Prior to founding MPS, Michael was a Senior Silicon Technology Developer at several analog IC companies, where he developed and patented key technologies, which set new standards in the Power Electronics industry. In order to execute his vision, he created groundbreaking enabling technologies using a fully integrated power process in a CMOS foundry. In May of 1998, a single-chip solution for powering CCFL backlighting in Notebooks was launched. The product substantially reduced the total solution cost and design complexity, as well as significantly improved power conversion. As a result, this product stormed the laptop market by taking 40% market share in 2003 and 80% in 2005. Immediately the company diversified into DC/DC products, which again reset the industry standard. In November 2004, Michael took the company IPO. Since then, the company has grown to 6 product lines with more than 1000 products and thousands of customers. In 2013, Michael fulfilled his vision: MPS introduced an industry first - a cost effective Monolithic Power Module that truly integrates an entire power system onto a single package, entering the industry into a new era of power management.
