2 Description
The TPS40400EVM-351 is designed to use a regulated 12-V bus to produce a regulated 1.2-V output at up to
20 A of load current. The TPS40400EVM-351 is designed to demonstrate the TPS40400 in a typical low-voltage
application while providing a number of test points to evaluate the performance of the TPS40400.
2.1 Typical Applications
• Smart Power Systems
• Power Supply Modules
• Communications Equipment
• Computing Equipment
