- Freewheeling Schottky diode is replaced with another MOSFET to reduce
conduction losses due to the voltage drop across the diode.
- Control MOSFET SC and Synchronous Rectification MOSFET SS are turned
on and off alternatively with a short dead time.
- Sometimes small Schottky diode is added in parallel to Sync FET to reduce
MOSFET body diode reverse-recovery and conduction losses.
