PTH12050 Series

Not for New Designs

33 W (6 A) Non-Isolated DC-DC Coverters

The PTH12050 series of non-isolated DC-DC converters complies with the Point-of-Load Alliance (POLA) standard. The converters offer some of the most advanced POL functions in the industry, including Auto-Track™ sequencing for controlled power-up/power-down of complex semiconductor devices such as DSPs, FPGAs and ASICs. Standard features include pre-bias startup, input undervoltage lockout, remote On/Off and auto resetting short-circuit protection.

There are two models in the PTH12050 series of converters, both of which have an input voltage range of 10.8 to 13.2 VDC. One model offers an output voltage that can be trimmed from 0.8 to 1.8 VDC, the other has an output that can be trimmed from 1.2 to 5.5 VDC, enabling a broad diversity of semiconductor power needs to be satisfied. Rated at 33 W, the converters offer up to 93% efficiency and can deliver up to 6 A. Available in through-hole horizontal mount and surface-mount versions, they have a small 0.5 x 0.87 inch (12.7 x 22.1 mm) footprint and an installed height of just 0.33 inch (8.5 mm).
