Operating Input Voltage 2.25 V to 5.5 V  
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.  
Output Voltage as Low as 0.7 V  
1% Internal 0.7 V Reference  
Predictive Gate DriveN-Channel MOSFET  
Drivers for Higher Efficiency  
The TPS4002x utilizes a proprietary Predictive Gate  
Drivetechnology 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  
Drivetechnology and charge pump/boost circuits  
combine to provide a highly efficient, smaller and less  
expensive converter.

Comparators with Power Good Indication  
Provide Output Status  
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.
