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

12v to 220v Inverter Schematic

I would like to learn on how to invert 12V DC to 220V AC for 100 watts that’s why I’m doing my research about this because I’m not an Electronic or even an Electrical Engineer.  So I need more info on how to do it right to avoid accident. By doing the research I found some techniques and tutorials on how to do it easy without deep understanding on it.

In this 12v inverter circuit diagram I used the IC 4047 – IRF540 instead of transistor 2N3055 because it is a good idea power output for 100W from the transformer 2-3A. For the information for those who did not know yet that AC can’t be stored for future use but DC can be stored for future use in a battery. The stored DC can be converted back to AC by using power inverters. Below is the schematic diagram of the inverter that I made.

I also created a circuit diagram inverting 12V DC to 220V AC for 500 Watts.
