SIMPLIFIED APPLICATION DIAGRAM
APPLICATIONS Networking Equipment Telecom Equipment Base Stations Servers DSP Power Power Modules DESCRIPTIONThe TPS4000x are controllers for low-voltage,
non-isolated synchronous buck regulators. These
controllers drive an N-channel MOSFET for the
primary buck switch, and an N-channel MOSFET
for the synchronous rectifier switch, thereby
achieving very high-efficiency power conversion. In
addition, the device controls the delays from main
switch off to rectifier turn-on and from rectifier
turn-off to main switch turn-on in such a way as to
minimize diode losses (both conduction and
recovery) in the synchronous rectifier with TI’s
proprietary Predictive Gate Drive� technology. The
reduction in these losses is significant and increases
efficiency. For a given converter power level, smaller
FETs can be used, or heat sinking can be reduced
or even eliminated.
