Abstract
A switching circuit having a low side driver providing a three-level low side drive signal keeps a low side power switch slightly on during a dead time between the low side power switch turn off and a high side power switch turn on, thus a current flowing through a body diode is mostly distributed to the slightly on low side power switch instead of the body diode.
