Equivalent & Substitute Parts Reference: PTH05020WAST
Part Overview
The PTH05020WAST from Texas Instruments is a Non-Isolated Point-of-Load (PoL) DC-DC Converter module, providing a single output with adjustable voltage between 0.8V and 3.6V and a maximum output current of 22A. It is designed for commercial ITE applications and features remote on/off functionality and integrated protection mechanisms. This DC-DC converter is currently classified as "Obsolete," making it necessary for engineers to identify alternative models that can meet existing and future design or replacement needs. All substitution candidates must match critical electrical, mechanical, and compliance parameters for direct design-in.
