Introduction
1.1
Description
TPS53114EVM-541 evaluation module is an example of a high-efficiency, single, synchronous buck
converter providing 1.20 V at 4 A from 5-V to 22-V input using the TPS53114 single-channel D-CAP2™
mode controller. The TPS53114 provides the user the ability to evaluate the performance of the
TPS53114 in a typical application including test points for simple, noninvasive monitoring of critical signals
within the design. This user’s guide contains a schematic, board layout, and bill of materials along with
typical performance characteristics and test methodology
