Texas Instruments DC-to-DC Converter Non-Isolated Step-Down Power Modules with adjustable output voltage.

The Texas Instruments PTH04000W series is a highly integrated, low-cost switching regulator module that delivers up to 3 A of output current. Occupying a small PCB area, the PTH04000W provides output current at a high efficiency and with minimal power dissipation, thereby eliminating the need for a heat sink. Their small size (0.75 inch ´ 0.5 inch), high efficiency, and low cost makes these modules practical for a variety of applications.
