NEW Product
The PTH05020 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, pre-bias start-up capability and efficiencies up to 96%. The
PTH05020 has an input voltage of 4.5 Vdc to 5.5 Vdc and offers a wide 0.8 Vdc to 3.6 Vdc
output voltage range with up to 22 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 °C unless otherwise stated
