Overview
The PTH04000WAZ is a highly integrated, low-cost switching regulator module produced by Texas Instruments. This module is designed to deliver up to 3 A of output current, making it suitable for a variety of applications. It features a small PCB footprint, measuring 0.75 inch × 0.5 inch, and operates with high efficiency, minimizing power dissipation and eliminating the need for a heat sink. The module supports input voltages ranging from 3 V to 5.5 V, allowing operation from either a 3.3-V or 5-V input bus. It can step down to voltages as low as 0.9 V from a 5-V input bus, with adjustable output voltage using a single external resistor.
