The TPS4002x family of dc-to-dc controllers are designed for non-isolated synchronous buck regulators, providing enhanced operaTIon and design flexability through user programmability.
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.
Design flexibility is provided through user programmability of such functions as: operating frequency, short circuit current detection thresholds, soft-start ramp time, and external synchronization frequency.
