Texas Instruments TPS546C20AEVM2-746 Converter Evaluation Module

Texas Instruments TPS546C20AEVM2-746 Converter Evaluation Module (EVM) is designed to demonstrate the stacking operation of the TPS546C20A. The TPS546C20A is a PMBus stackable synchronous buck converter. The evaluation module uses two TPS546C20A stacked devices. The phase converters on the evaluation module provide a 0.9V output at up to 70A from a 12V input bus. While using the TPS546C20A in a two-phase low output voltage application, the evaluation module provides several test points to evaluate the performance of the devices. The Texas Instruments TPS546C20AEVM2-746 can be modified into two separated single-phase buck converters by changing the components assembled.
