The PTH12050 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 efficiencies up to 93%. The PTH12050 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.
