SPECIFICATIONS

The PTH05050 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 pre-bias start-up capability and efficiencies up to 95%. The PTH05050 has an

input voltage of 4.5 Vdc to 5.5 Vdc and offers a wide 0.8 Vdc to 3.6 Vdc output voltage

range with up to 6 A output current, which allows for maximum design flexibility and a

pathway for future upgrades.
