DESCRIPTION

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. The operating

frequency is programmable using a single resistor over a

frequency range of 100 kHz to 1 MHz. Higher operating

frequencies yield smaller component values for a given

converter power level as well as faster loop closure.
