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 鈥?0擄C to 125擄C.
