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 a switching controller that does not include suitable

on-chip 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.
