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.
