Description

The PTH04000WAH is a 10.8W through hole-mount non-isolated Adjustable Switching Regulator with Auto-Track™ sequencing. The PTH04000W is a highly integrated switching regulator module that delivers up to 3A 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. The input voltage range of the PTH04000W is from 3 to 5.5V, allowing operation from either a 3.3 or 5V input bus. Using state-of-the-art switched-mode power-conversion technology, the PTH04000W can step down to voltages as low as 0.9V from a 5V input bus, with typically less than 1W of power dissipation. The output voltage can be adjusted to any voltage over the range, 0.9 to 3.6V, using a single external resistor. This feature simplifies the task of supply voltage sequencing in a power system by enabling modules to track each other or any external voltage, during power up and down.
