description
The TPS2836 and TPS2837 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 minimum 2-A peak currents into large capacitive loads. The high-side driver
can be configured as ground-reference or as floating-bootstrap. 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 TPS2836 has a noninverting input, while the TPS2837 has an inverting input. These drivers, available in
8-terminal SOIC packages, operate over a junction temperature range of − 40°C to 125°C.
