TPS2831PWPR

Product Summary

The TPS2831PWPR is a MOSFET driver for synchronous-buck power stages. The TPS2831PWPR is 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 TPS2831PWPR driver has additional control functions: ENABLE, SYNC, and CROWBAR. Both drivers are off when ENABLE is low. The driver is configured as a nonsynchronous-buck driver, disabling the low side driver when SYNC is low. The TPS2831PWPR has an inverting input. The TPS2831PWPR driver is available in 14-terminal SOIC and thermally-enhanced TSSOP PowerPAD. packages, and operate over a virtual junction temperature range of -40℃ to 125℃.
