FDMF5820DC Smart Power Stage

Have you done creating high current power stage circuit diagram using the FDMF5820DC? Recently, I decided to create one by following the diagram below with instruction of course.  It is the next generation family of Fairchild with fully optimized, ultra-compact, integrated MOSFET plus driver power stage solution for high-current, high frequency, synchronous buck, DC-DC applications.

Check some features of FDMF5820DC.

• Ultra-Compact 5 mm x 5 mm PQFN Copper-Clip Package with Flip Chip Low-Side MOSFET and Dual Cool Architecture

• High Current Handling: 60 A

• 3-State 3.3 V PWM Input Gate Driver

• Dynamic Resistance Mode for Low-Side Drive (LDRV) Slows Low-Side MOSFET during Negative Inductor Current Switching

• Auto DCM (Low-Side Gate Turn Off) Using ZCD# Input

• Thermal Monitor for Module Temperature Reporting

• Programmable Thermal Shutdown (P_THDN)

• HS-Short Detect Fault# / Shutdown

• Dual Mode Enable / Fault# Pin

• Internal Pull-Up and Pull-Down for ZCD# and EN Inputs, respectively

• Fairchild PowerTrench® MOSFETs for Clean Voltage Waveforms and Reduced Ringing

• Fairchild SyncFETTM Technology (Integrated Schottky Diode) in Low-Side MOSFET

• Integrated Bootstrap Schottky Diode
