TPS2830, TPS2831 are fast synchronous-buck MOSFET drivers with deadtime control. These devices are ideal for designing high-performance power supplies using a switching controller that does not include suitable MOSFET drivers on the chip. The drivers are designed to deliver 2.4A peak currents into large capacitive loads. Higher currents can be controlled by using multiple drivers in a multiphase configuration. The high-side driver can be configured as a ground-reference driver or as a floating bootstrap driver. 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 TPS2830/31 drivers have additional control functions: ENABLE, SYNC, and CROWBAR.
The TPS2830 and TPS2831 are MOSFET drivers designed for high-performance synchronous-buck power stages. They deliver up to 2.4-A peak output current into large capacitive loads and can be configured as ground-reference or floating bootstrap drivers. The devices include an adaptive deadtime control circuit to eliminate shoot-through currents during switching transitions.
