and General-Purpose Circuits 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 Г— 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-Trackв„ў 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.

Power Two Xilinx(TM) LX240 Virtex-6(TM) Devices
PDF, 63 Kb, Archivo publicado: abr 20, 2010
This reference design is intended to help designers wishing to use two of the new Virtex-6™ LX240 FPGA along with DDR memory and other optional circuitry in their designs. It provides nine rails of lower voltage with an input of 12 volts. The use of PTH T2 modules provides a high-performance solution for good transient response and tight regulation while conserving valuable board space.
