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.
