The PTH12010 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%. The PTH12010 has an input voltage of
10.8 Vdc to 13.2 Vdc and offers a wide 1.2 Vdc to 5.5 Vdc output voltage range with up to
12 A output current, which allows for maximum design flexibility and a pathway for future
upgrades.
