NEW Product
The dual output DDR12-25D08-AJ is specially designed to meet the power needs of
double data rate memory DIMMS and associated memory control logic. The Vtt
output tracks the Vddq output, while the Vtt output can sink current as required by
logic terminations. This converter offers typical efficiencies greater than 84% when
operated at 50% load or greater. This model features a wide input range as well as
trimmable output voltages. Remote sense on Vddq and remote ON/OFF facilities are
included as standard, and the converter is protected against over-current and over-
voltage conditions.
All specifications are typical at nominal input, full load at 25 °C unless otherwise stated
