some advice please , I wanna build a buck converter with synchronous rectification with a complementary pair (N+P) MOSFET, but I couldn't find a specific gate driver, almost everything I found was about dual N-channel, Or it's just so simple that doesn't exist?, because I would like to have a gate driver for complementary pair with adaptive shoot-through and dead-time protection. some of you know about a mosfet gate driver for complementary pair? any IC. thanks.
Dear Freddy,
Complementary power MOS transistors are used to build high efficiency class D audio amplifiers. There are integrated circuits chips developed to drive them efficiently avoiding the shoot through effect by adjusting the dead time.
An example of the driver you search for is the chip Si8241/44 Audio Gate Driver.
For more information please follow the link:

wish you ssuccess
thanks, for example this IC TPS43000 use a complementary pair MOSFET for Buck and Boost converter.
