PTH12040
The PTH12040 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鈥檚, FPGA鈥檚 and
ASIC鈥檚 requiring controlled power-up and power-down Other industry leading
features include margin up/down controls and efficiencies up to 96%. The
PTH12040 has an input voltage of 8 Vdc to 14 Vdc and offers a wide 0.8 Vdc to
5.5 Vdc output voltage range with up to 50 A output current, which allows for
maximum design flexibility and a pathway for future upgrades.
All specifications are typical at nominal input, full load at 25 擄C unless otherwise stated
