The PTH12020 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 95% . The PTH12020
has an input voltage of 10.8 Vdc to 13.2 Vdc and offers a wide output voltage range
adjustable with external trim resistor, allowing for maximum design flexibility and a
pathway for future upgrades.
