NEW Product

File Name: pth12040w.pdf Rev (03): 19 Dec 2005

The PTH12040 is a next generation series of non-isolated dc-dc converters offering

some of the most advanced POL features available in the industry. The primary new

feature provides for sequencing between multiple modules, a function, which is

becoming a necessity for powering advanced silicon including DSP’s, FPGA’s and

ASIC’s requiring controlled power-up and power-down Other industry leading

features include margin up/down controls and efficiencies up to 96%. The

PTH12040 has an input voltage of 8 Vdc to 14 Vdc and offers a wide 0.8 Vdc to

5.5 Vdc output voltage range with up to 50 A output current, which allows for

maximum design flexibility and a pathway for future upgrades.
