TPS40200EVM-001: 3.3V @ 2.5A, 8 ~ 16 Vin

The TPS40200EVM-001 evaluation module (EVM) uses the TPS40200 nonsynchronous buck converter to provide a resistor-selected 3.3-V output voltage that delivers up to 2.5 A from a 12-V input bus. The EVM operates from a single supply and uses a single P-channel power FET and Schottky diode to produce a low-cost buck converter. The part operates at a 300-kHz clock frequency with provision for external frequency synchronization.

TPS40200EVM-001 is designed to operate with an 8-V to 16-V input and to produce a regulated 3.3-V output with a load current from 0.125 A to 2.5 A. The TPS40200EVM-001 demonstrates the use of the TPS40200 in a typical buck converter application.

The board sacrifices some packing density to provide sample test points for module evaluation. This EVM can be modified to support output voltages from 0.7 V to 5 V by changing a single feedback resistor. The TPS40200EVM-001 has been built to the sample application as described in the Application Information section of the TPS40200 data sheet (SLUS659).
