ZSPM9015 Ultra-Compact, High-Performance, High-Frequency DrMOS Device Brief Description Benefits The ZSPM9015 is ZMDI’s next-generation, fully optimized, ultra-compact, integrated MOSFET plus driver power stage solution for high-current, highfrequency, synchronous buck DC-DC applications. The ZSPM9015 integrates a driver IC, two power MOSFETs, and a bootstrap Schottky diode into a thermally enhanced, ultra-compact 6x6mm package. With an integrated approach, the complete switching power stage is optimized with regard to driver and MOSFET dynamic performance, system inductance, and power MOSFET RDS(ON). The ZSPM9015 uses innovative high-performance MOSFET technology, which dramatically reduces switch ringing, eliminating the need for a snubber circuit in most buck converter applications. A driver IC with reduced dead times and propagation delays further enhances the performance. A thermal warning function indicates if a potential over-temperature situation (>150°C) has occurred. An automatic thermal shutdown activates if an over-temperature condition (>180°C) is detected. The ZSPM9015 also incorporates a Zero Current Detection Mode (ZCD) for improved light-load efficiency and provides a tristate 3.3V and 5V PWM input for compatibility with a wide range of PWM controllers. Improved efficiency with zero current detection Clean switching waveforms with minimal ringing Based on the Intel® 4.0 DrMOS standard 72% space-saving compared to conventional discrete solutions High current handling Optimized for use with ZMDI’s ZSPM1000 true digital PWM controller Available Support ZSPM8015-KIT: Evaluation Kit for ZSPM9015 Physical Characteristics Operation temperature: 0°C to +150°C VIN: 4.5V to 25V (typical 12V) IOUT: up to 35A Low-profile SMD package: 6mmx6mm QFN40 ZMDI green packaging and RoHS compliant Typical Application The ZSPM9015 DrMOS is compatible with ZMDI’s ZSPM1000, a leading-edge configurable digital power-management system controller designed for non-isolated point-of-load (POL) supplies. Features High-current handling: up to 35A PWM input capable of 3.3V and 5V Optimized for switching frequencies up to 1MHz Zero-current detection and under-voltage lockout (UVLO) Thermal shutdown and warning flag for overtemperature conditions Driver output disable function (DISB# pin) Integrated Schottky diode technology in the low-side MOSFET Integrated bootstrap Schottky diode Adaptive gate drive timing for shoot-through protection For more information, contact ZMDI via SPM@zmdi.com. © 2013 Zentrum Mikroelektronik Dresden AG — Rev. 1.10 — August 5, 2013.
