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
