PTH12020 Series

99 Watt (18 Amp) Non-Isolated DC-DC Converters

The PTH12020 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, and voltage margining. Standard features include pre-bias startup, input undervoltage lockout, remote sense, remote On/Off and auto resetting short-circuit protection.

There are two models in the PTH12020 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. The 0.8 to 1.8 V output converter offers up to 89% efficiency while the higher output voltage model can achieve up to 95%. Both converters are rated at 99 watts output power and can deliver up to 18 amps. Available in through-hole horizontal mount and surface-mount versions, they have a small 0.87 x 1.5 inch (22.1 x 38 mm) footprint and an installed height of just 0.35 inch (9 mm).
