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 High Current Handling: 60 A FDMF5820TDC integrates a driver IC with a bootstrap Schottky diode, two power MOSFETs, and a thermal 3-State 3.3 V PWM Input Gate Driver monitor into a thermally enhanced, ultra-compact, 5 mm Dynamic Resistance Mode for Low-Side Drive x 5 mm package. (LDRV) Slows Low-Side MOSFET during Negative With an integrated approach, the SPS switching power Inductor Current Switching stage is optimized for driver and MOSFET dynamic Auto DCM (Low-Side Gate Turn Off) Using performance, minimized system inductance, and power ZCD Input MOSFET R . The SPS family uses Fairchild s high- DS(ON) performance PowerTrench MOSFET technology, Thermal Warning (THWN ) to Warn Over- which reduces switch ringing, eliminating the need for a Temperature of Gate Driver IC 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. The FDMF5820TDC incorporates an Auto- EN Inputs, respectively DCM Mode (ZCD ) for improved light-load efficiency. Fairchild PowerTrench MOSFETs for Clean The FDMF5820TDC also provides a 3-state 3.3 V PWM Voltage Waveforms and Reduced Ringing input for compatibility with a wide range of PWM controllers.
