The TPS51513EVM-549 evaluation module (EVM) is a single-phase, D-CAP+™ synchronous buck
converter providing 3-bit VID with 0.70-V to 1.05-V output range at up to 20 A from a 12-V input bus. The EVM uses the TPS51513 synchronous buck controller with selectable 250/300/350/500-kHz switching frequency. The TPS51513EVM-549 is designed to use a regulated 12-V (8-V to 14-V) bus to produce a high-current, regulated variable output at up to 20 A of the load current. The output voltage varies from 0.70 V to 1.05 V via a 3-bit VID digital-to-analog converter (DAC). The TPS51513EVM-549 is designed to demonstrate the TPS51513 in a typical low-voltage application while providing a number of test points to evaluate the performance of the TPS51513.
