DESCRIPTION
The PTH08000W is a highly integrated, low-cost switching regulator module that delivers up to 2.25 A of output
current. The PTH08000W sources output current at a much higher efficiency than a TO-220 linear regulator IC,
eliminating the need for a heatsink. The small size (0.75 inch × 0.5 inch) and flexible operation creates value for
a variety of applications.

The input voltage range of the PTH08000W is 4.5 V to 14 V, allowing operation from either a 5-V or 12-V input
bus. Using state-of-the-art switched-mode power-conversion technology, the PTH08000W can step down to
voltages as low as 0.9 V from a 5-V input bus, with less than 1 W of power dissipation. The output voltage can
be adjusted to any voltage over the range, 0.9 V to 5.5 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. Operating
features include an undervoltage lockout (UVLO), on/off inhibit, overcurrent protection, and overtemperature
protection. Target applications include telecommunications, test and measurement applications, and high-end
consumer products. This product is available in both through-hole and surface-mount package options, including
tape and reel. The PTH08000W is compatible with TI's roadmap for RoHS and lead-free compliance.
