... BODY-BRAKING® MODE International Rectifier’s Body-Braking® operation mode in which two MOSFETs are turned off. When the synchronous MOSFET is off, the higher voltage across the Shottky diode in parallel helps discharging the inductor current faster, which reduces the output voltage overshoot. The Body-Braking® ...
