NEW Product

File Name: pth04040.pdf Rev: 27 Jun 2006

The PTH04040 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

PTH04040 has an input voltage of 2.95 Vdc to 5.5 Vdc and offers a wide 0.8 Vdc to

2.5 Vdc output voltage range with up to 60 A output current, which allows for

maximum design flexibility and a pathway for future upgrades.
