NEW Product

File Name: pth12030.pdf Rev (07): 19 Dec 2005

The PTH12030 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 94.5%. The PTH12030 has an

input voltage of 10.2 Vdc to 13.8 Vdc and offers a wide output voltage range

adjustable with external trim resistor, allowing for maximum design flexibility and a

pathway for future upgrades.
