Rochester Electronics PMIC - Gate Drivers TPS2831D

The TPS2831D is a high-side MOSFET driver designed for synchronous-buck power stages, capable of delivering a typical peak output current of 2.4 A. It operates within a supply voltage range of 4.5 V to 15 V and features an internal Schottky bootstrap diode for improved efficiency. The driver supports both ground-reference and floating bootstrap configurations, making it versatile for various applications. Key features include adaptive dead-time control to prevent shoot-through currents, a CROWBAR function for over-voltage protection, and SYNC control for synchronous or nonsynchronous operation. The device has a maximum rise/fall time of 50 ns and a maximum propagation delay of 100 ns with a 3.3 nF load. It operates over a virtual junction temperature range of -40°C to 125°C and is available in both SOIC and TSSOP PowerPAD packages. This driver is suitable for high-current single or multiphase power supplies, making it a reliable choice for engineers looking to enhance their power management designs.
