DRESDEN, GERMANY- ZMD AG (ZMDI), a Dresden-based semiconductor company that specializes in enabling energy-efficient solutions, today announces the product release of an energy-efficient DC/DC regulator for non-isolated step-down applications. The ZSPM4022 is a single-phase buck regulator with integrated driver and power FETs, capable of leveraging a wide input voltage range and supporting up to 12A of output current. As a global supplier of analog and mixed-signal solutions for automotive, industrial, medical, information technology and consumer applications, ZMDI has developed the ZSPM4022 to expand its family of analog power solutions targeting simple, high performance single-phase applications including server, telecommunications, storage and consumer devices.
The new ZSPM4022 provides high-efficiency DC/DC conversion for all load ranges, with the capability to automatically run in continuous or discontinuous modes based upon load requirements. High efficiency at low load is accomplished by supporting discontinuous mode operation where the regulator shuts down all non-essential circuits and minimizes the supply current draw. During discontinuous mode, the total power supply current is only 450µA, allowing the regulator to achieve high efficiency in light load applications. In addition, the highly integrated design of the regulator enables improved design-cycles, bill-of-materials cost reduction, and savings due to the small package footprint.
"The ZSPM4022 represents ZMDI's focus on improved energy-efficiency. We designed the ZSPM4022 to provide our customers with simple, easy to design, highly integrated DC/DC conversion with improved efficiency enabling customers to achieve a quick time-to-market solution for load requirements up to 12A," said Adrian Ward, Architect of Analog Power at ZMDI. "Unlike many integrated regulators available today, the ZSPM4022 focuses on providing capabilities for higher load levels and supporting a wide input voltage range, thus allowing customers flexibility in their system designs whilst maintaining a small footprint."
