TPS40077EVM-001 的说明
The TPS40077EVM-001 evaluation module (EVM) is a synchronous buck converter providing a fixed 1.8 V output at up to 10 A from a 12 V input bus. The EVM is designed to start up from a single supply; no additional bias voltage is required for start-up. The TPS40077 Reduced Pin Count Synchronous Buck Controller used in the EVM employs predictive gate drive. This feature provides improved efficiency by eliminating shoot-through switching current,and minimizing the reverse-conduction time of the synchronous rectifier FET.
