description
The TPS2832 and TPS2833 are MOSFET drivers for synchronous-buck power stages. These devices are ideal
for designing a high-performance power supply using switching controllers that do not have MOSFET drivers.
The drivers are designed to deliver 2.4-A peak currents into large capacitive loads. 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 TPS2832 has a noninverting input. The TPS2833 has an inverting input. The TPS2832/33 drivers, available
in 8-terminal SOIC packages, operate over a junction temperature range of −40°C to 125°C.
