The TPS4002x utilizes a proprietary Predictive Gate Drive technology to minimize the diode conduction losses associated with the high-side and synchronous rectifier N-channel MOSFET transistions. The integrated charge pump with boost circuit provides a regulated 5-V gate drive for both the high side and synchronous rectifier N-channel MOSFETs. The use of the Predictive Gate Drive technology and charge pump/boost circuits combine to provide a highly efficient, smaller and less expensive converter.
