Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore ( ), the underscore ( ) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore ( ). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

The 3-State 5 V PWM Input Gate Driver FDMF5839 integrates a driver IC with a bootstrap Schottky diode, two power MOSFETs, and a thermal Dynamic Resistance Mode for Low-Side Drive monitor into a thermally enhanced, ultra-compact 5 mm (LDRV) Slows Low-Side MOSFET during Negative x 5 mm package. Inductor Current Switching With an integrated approach, the SPS switching power Auto DCM (Low-Side Gate Turn Off) Using stage is optimized for driver and MOSFET dynamic ZCD Input performance, minimized system inductance, and power Thermal Warning (THWN ) to Warn Over- MOSFET RDS(ON). The SPS family uses Fairchild s high- Temperature of Gate Driver IC performance PowerTrench MOSFET technology, which reduces switch ringing, eliminating the need for a Thermal Shutdown (THDN) snubber circuit in most buck converter applications. HS-Short Detect Fault / Shutdown A driver IC with reduced dead times and propagation Dual Mode Enable / Fault Pin delays further enhances the performance. A thermal warning function warns of a potential over-temperature Internal Pull-Up and Pull-Down for ZCD and situation. A thermal shutdown function turns off the EN Inputs, respectively driver if an over-temperature condition occurs. The Fairchild PowerTrench MOSFETs for Clean FDMF5839 incorporates an Auto-DCM Mode (ZCD ) for Voltage Waveforms and Reduced Ringing improved light-load efficiency. The FDMF5839 also provides a 3-state 5 V PWM input for compatibility with Fairchild SyncFET Technology (Integrated a wide range of PWM controllers. Schottky Diode) in Low-Side MOSFET Integrated Bootstrap Schottky Diode Applications Optimized / Extremely Short Dead-Times Notebook, Tablet PC and Ultrabook Under-Voltage Lockout (UVLO) on VCC Servers and Workstations, V-Core and Non-V-Core Optimized for Switching Frequencies up to 1.5 MHz DC-DC Converters PWM Minimum Controllable On-Time: 30 ns Desktop and All-in-One Computers, V-Core and Low Shutdown Current: < 3 A Non-V-Core DC-DC Converters Optimized FET Pair for Highest Efficiency: High-Performance Gaming Motherboards 10 ~ 15% Duty Cycle High-Current DC-DC Point-of-Load Converters Operating Junction Temperature Range: Networking and Telecom Microprocessor Voltage -40C to +125C Regulators Fairchild Green Packaging and RoHS Compliance Small Form-Factor Voltage Regulator Modules Automotive Qualified to AEC-Q100 (F085 version) Automotive-qualified Systems (F085 version) Ordering Information Part Number Current Rating Package Top Mark FDMF5839 35 A 31-Lead, Clip Bond PQFN SPS, 5.0 mm x 5.0 mm Package 5839 FDMF5839 F085 35 A 31-Lead, Clip Bond QFN SPS, 5.0 mm x 5.0 mm Package TBD 2013 Semiconductor Components Industries, LLC www.fairchildsemi.com FDMF5839 Rev. 1.9 www.onsemi.com
