Energy-efficient DC/DC regulator provides 12A output

ZMDI has developed the ZSPM4023 to expand its family of analog power solutions targeting simple, high performance single-phase applications including server, telecommunications, storage and consumer devices.

The ZSPM4023 is an extension to the previously announced ZSPM4022; it allows higher input voltage support while enabling the same high performance, highly efficient DC/DC designs as is required by today’s applications. The ZSPM4023 provides high-efficiency DC/DC conversion for all load ranges, with the capability to automatically run in continuous or discontinuous modes based on load requirements. High efficiency at low load is accomplished by supporting discontinuous mode operation in which the regulator shuts down all non-essential circuits and minimises the supply current draw. During discontinuous mode, the total power supply current is only 450µA. In addition, the highly integrated design of the regulator enables improved design-cycles, bill-of-materials cost reduction and footprint savings.

“The ZSPM4023 exemplifies ZMDI’s focus on improved energy-efficiency. The ZSPM4023 and the previously announced ZSPM4022 provide simple, easy-to-design, highly integrated DC/DC conversion with improved efficiency, enabling customers a quick time-to-market solution for load requirements up to 12A,” said Adrian Ward, Architect of Analog Power, ZMDI. “The DC/DC family of the ZSPM4023 and ZSPM4022 focuses on offering capabilities for higher load levels and supporting a wide input voltage range, thus allowing customers flexibility in their system designs while maintaining a small footprint.”

The ZSPM4023 is in full production. It is available in three variants based upon output load rating: ZSPM4023-12 (12A), ZSPM4023-09 (9A), and ZSPM4023-06 (6A). Parts and Evaluation Kit are available from ZMDI. In 1,000 unit quantities, the ZSPM4023-12 is priced at €1,46 or $2.05 (USD) each.
