DESCRIPTION
The PTH04000W 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.

The input voltage range of the PTH04000W 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 output
voltage can be adjusted to any voltage over the range, 0.9 V to 3.6 V, using a single external resistor. This series
includes Auto-Track sequencing. 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 power down.
Other operating features include an undervoltage lockout (UVLO), on/off inhibit, output overcurrent protection,
and overtemperature protection. Target applications include telecommunications, test and measurement
applications, and high-end consumer products. The modules are available in both through-hole and sur-
face-mount package options, including tape and reel. The PTH04000W is also compatible with TI's roadmap for
RoHS and lead-free compliance.
