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.
