DESCRIPTION

Source-Only Current or Source/Sink Current

OUT

The TPS4000x are controllers for low-voltage,

10-Lead MSOP PowerPadt Package for

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 Drivet 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.
