Description

The TPS54160EVM-230 evaluation module (EVM) helps designers evaluate the operation and performance of the TPS54160 DC/DC converter. This converter is a wide input voltage (3.5 - 60V), 2.5MHz, non-synchronous, externally compensated, step down converter capable of 1.5A of output current. The TPS54160EVM-230 provides two independent DC/DC converters based on the TPS54160. The converter at the top of the board (top converter) is designed to operate from a nominal 42VDC ±25% input voltage source. This input voltage range is typical for input supplies derived from rectified 24VAC sources. The top converter provides a 5.0V output and up to 1.5A of output current. The top converter highlights a small solution size by using 0402 components with the minimum number of parts needed to provide a fully functional DC/DC converter complete with a programmed enable/disable voltage and soft start features. The converter at the bottom of the board (bottom converter) is designed to operate from 6.0V to 60V, the maximum recommended input voltage the TPS54160. The bottom converter provides a 3.3V output with up to 1.5A of output current. The bottom converter has additional component footprints that can be used by the designer to implement a variety of TPS54160 solutions.
