description  
The TPS2830 and TPS2831 are MOSFET drivers for synchronous-buck power stages. These devices are ideal  
for designing a high-performance power supply using a switching controller that does not include suitable  
MOSFETdrivers on the chip. The drivers are designed to deliver 2.4-A peak currents into large capacitive loads.  
Higher currents can be controlled by using multiple drivers in a multiphase configuration. The high-side driver  
can be configured as a ground-reference driver or as a floating bootstrap driver. An adaptive dead-time control  
circuit eliminates shoot-through currents through the main power FETs during switching transitions, and  
provides high efficiency for the buck regulator. The TPS2830/31 drivers have additional control functions:  
ENABLE, SYNC, and CROWBAR. Both drivers are off when ENABLE is low. The driver is configured as a  
nonsynchronous-buck driver when SYNC is low. The CROWBAR function turns on the low-side power FET,  
overriding the IN signal, for over-voltage protection against faulted high-side power FETs.  
The TPS2830 has a noninverting input. The TPS2831 has an inverting input. The TPS2830/31 drivers are  
available in 14-terminal SOIC and TSSOP packages and operate over a junction temperature range of –40°C  
to 125°C.
