Using the TPS40077EVM-001 12-V Input, 1.8-V Output,
10-A Synchronous Buck Converter
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.
