Product Summary

The PTH04000WAZ is a highly integrated, low-cost switching regulator module that delivers up to 3 A of output current. Occupying a small PCB area, the PTH04000WAZ 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 x 0.5 inch), high efficiency, and low cost makes these modules practical for a variety of applications. The input voltage range of the PTH04000WAZ is from 3 V to 5.5 V, allowing operation from either a 3.3-V or 5-V input bus. Using state-of-the-art switched-mode power-conversion technology, the PTH04000W can step down to voltages as low as 0.9 V from a 5-V input bus, with typically less than 1 W of power dissipation. The PTH04000WAZ is ideal for: telecommunications, instrumentation, and general-purpose circuits.
