Next-Generation DrMOS Device with Enhanced Light-Load Efficiency

June 05, 2013 by Jeff Shepard

ZMD AG (ZMDI) announced the release of the ZSPM9015, a next-generation, fully optimized, ultra-compact, integrated MOSFET-plus-driver (DrMOS) power stage solution for energy-efficient, high-current, high-frequency, synchronous buck dc-dc applications. As a global supplier of analog and mixed-signal solutions for automotive, industrial, medical, information technology and consumer applications, ZMDI is expanding its smart power management portfolio with the ZSPM9015, a new product for non-isolated dc-dc point-of-load (POL) supply applications.

In combination with ZMDI's compatible smart power management product family, the ZSPM9015 enables area-constrained and high-performance applications, such as servers, storage units, processor boards, field-programmable gate array (FPGA) boards and others. The DrMOS device is compatible with ZMDI's ZSPM10xx family of leading-edge, configurable digital power management system controllers for non-isolated POL supplies and other pulse-width modulation (pwm) controllers. The ZSPM9015 is available in an ultra-compact 40-pin QFN package (6mm x 6mm) and provides a 72% space saving compared to conventional discrete solutions

"The ZSPM9015 provides our customer with additional design flexibility for developing efficient POL systems with new features such as zero current detection for improved light-load efficiency and automatic thermal shutdown," stated Bernhard Huber, Business Line Manager for Power and Analog at ZMDI. "With this further expansion of our product portfolio, we want to extend our product offering of leading-edge and easy-to-use POL devices to provide our customers with various tools for the rapid development of smart power management solutions."

ZSPM9015 DrMOS features: Zero Current Detection Mode for improved light-load performance; High current handling with IOUT up to 35A; VIN of 4.5V to 25V (typical 12V); Operation temperature of 0°C to 150°C; Switching frequency up to 1MHz; Extended pwm input range supports both 3.3V and 5V; Under-voltage lockout, thermal warning and thermal shutdown for improved system reliability; and an open-loop evaluation board is available for the ZSPM9015.

The ZSPM9015 is in full production. Parts and open-loop evaluation boards are available from ZMDI. For 1,000 pieces, the ZSPM9015 is priced at EUR 1.63 or USD 2.28 per unit.
