ZSPM9015 Ultra-Compact, High-Performance, High-Frequency DrMOS Device Datasheet Brief Description Benefits The ZSPM9015 is IDTs next-generation, fully Improved efficiency with zero current detection optimized, ultra-compact, integrated MOSFET plus Clean switching waveforms with minimal ringing driver power stage solution for high-current, high- Based on the Intel 4.0 DrMOS standard frequency, synchronous buck DC-DC applications. 72% space-saving compared to conventional The ZSPM9015 integrates a driver IC, two power discrete solutions MOSFETs, and a bootstrap Schottky diode into a High current handling thermally enhanced, ultra-compact 6x6mm package. Optimized for use with IDTs ZSPM1000 true With an integrated approach, the complete switching digital PWM controller power stage is optimized with regard to driver and MOSFET dynamic performance, system inductance, and power MOSFET R . The ZSPM9015 uses DS(ON) Available Support innovative high-performance MOSFET technology, ZSPM8015-KIT: Evaluation Kit for ZSPM9015 which dramatically reduces switch ringing, eliminat- ing the need for a snubber circuit in most buck converter applications. Physical Characteristics A driver IC with reduced dead times and propagation Operation temperature: 0C to +150C delays further enhances the performance. A thermal V : 4.5V to 25V (typical 12V) IN warning function indicates if a potential over-temper- I : up to 35A OUT ature situation (>150C) has occurred. An automatic thermal shutdown activates if an over-temperature Low-profile SMD package: 6mmx6mm QFN40 condition (>180C) is detected. The ZSPM9015 also IDT green packaging and RoHS compliant incorporates a Zero Current Detection Mode (ZCD) for improved light-load efficiency and provides a tri- state 3.3V and 5V PWM input for compatibility with a Typical Application wide range of PWM controllers. The ZSPM9015 DrMOS is compatible with IDTs 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 over- temperature 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 1 January 25, 2016 ZSPM9015 Ultra-Compact, High-Performance, High-Frequency DrMOS Device Datasheet ZSPM9015 Block Diagram BOOT VIN DBoot Typical Applications VCIN UVLO High-performance gaming (Q1) motherboards HS Power GH PWM GH Level Shift Compact blade servers, MOSFET Logic Vcore and non-Vcore GH DC-DC converters LOGIC CGND Desktop computers, PHASE Vcore and Non-Vcore Anti-Cross DC-DC converters Conduction ZCD EN VSWH Workstations V CIN High-current DC-DC (Q2) point-of-load converters GL GL LS Power DISB Logic MOSFET Networking and telecom microprocessor voltage GL regulators Thermal Thermal THWN Warning Shutdown Small form-factor voltage ZSPM9015 regulator modules PGND Ordering Information Product Sales Code Description Package ZSPM9015ZI1R ZSPM9015 RoHS-Compliant QFN40 Junction temperature range: 0C to 150C Reel ZSPM8015-KIT Evaluation Kit for ZSPM9015 Kit 2016 Integrated Device Technology, Inc. 2 January 25, 2016
