DESCRIPTIONThe 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.
