DC-DC CONVERTERS Tracking Dual Output 1
2 YEAR WARRANTY
All specifications are typical at nominal input, full load at 25 °C unless otherwise stated SPECIFICATIONS
- High current dual-output power module for DDR memory
- Single compact module provides 25 A @ 2.5 V for V ddq supply and 8 A @ 1.25 V for V tt termination
- Tracking dual output voltages (1.25 V @ 8 A, 2.5 V @ 25 A)
- Output voltage remote sense (only on V ddq)
- Sink capability for logic terminations
- Power good output signal
- Overvoltage protection
- Overcurrent protection
- Remote ON/OFF
- Available RoHS compliant 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 V tt 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 V ddq and remote ON/OFF facilities are included as standard, and the converter is protected against over-current and over- voltage conditions.
