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 Clean Switching Waveforms with Minimal Ringing FDMF6706B integrates a driver IC, two power MOSFETs, and a bootstrap Schottky diode into a thermally High-Current Handling enhanced, ultra-compact 6x6 mm PQFN package. Features With an integrated approach, the complete switching power stage is optimized for driver and MOSFET Over 93% Peak-Efficiency dynamic performance, system inductance, and power MOSFET R . XS DrMOS uses Fairchild s high- High-Current Handling of 45 A DS(ON) performance PowerTrench MOSFET technology, High-Performance PQFN Copper-Clip Package which dramatically reduces switch ringing, eliminating the snubber circuit in most buck converter applications. 3-State 3.3 V PWM Input Driver A new driver IC with reduced dead times and Skip-Mode SMOD (Low-Side Gate Turn Off) Input propagation delays further enhances performance. A Thermal Warning Flag for Over-Temperature thermal warning function warns of potential over- Condition temperature situations. FDMF6706B also incorporates features such as Skip Mode (SMOD) for improved light- Driver Output Disable Function (DISB Pin) load efficiency, along with a Three-state 3.3 V PWM Internal Pull-Up and Pull-Down for SMOD and input for compatibility with a wide range of PWM DISB Inputs, Respectively controllers.
