The PTV12020 is a non-isolated dc-dc converter from Artesyn under the Point of Load
Alliance (POLA) standard. The vertical mounting option of the PTV12020 module provides
performance in less than 20% of the space that is required by alternative solutions. The
Auto-Track™ 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. The PTV12020 has an input
voltage of 10.8 Vdc to 13.2 Vdc and offers a wide 1.2 Vdc to 5.5 Vdc for suffix ‘W’ and
0.8 Vdc to 1.8 Vdc for suffix ‘L’ output voltage range with up to 16 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
