DDR12-25D08-A

DDR12 Series Dual output DC-DC CONVERTERS Tracking Dual Output 1 NEW Product 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 termination tt 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 V output, while the V output can sink current as required by ddq tt 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 and remote ON/OFF facilities are ddq included as standard, and the converter is protected against over-current and over- voltage conditions. 2 YEAR WARRANTY All specifications are typical at nominal input, full load at 25 C unless otherwise stated SPECIFICATIONS OUTPUT SPECIFICATIONS - V INPUT SPECIFICATIONS - Contd. ddq Voltage adjustability 2.32-2.75 Vdc Input reflected ripple (See Note 4) 100 mA (pk-pk) Output setpoint accuracy Using 1% trim resistors 2.5% Remote ON/OFF Logic compatibility Open collector ref to -input Line regulation Low line to high line 0.1% ON >2.0 Vdc OFF <0.8 Vdc Load regulation Minimum load to full load +0%/-1.0% Start-up time Power up <20 ms Cross regulation 0.4% (See Note 5) Remote ON/OFF <20 ms Temperature Co-efficient 0.2 mV/C EMC CHARACTERISTICS Ripple and noise 5 Hz to 20 MHz 50 mV pk-pk (See Note 1) Electrostatic discharge EN61000-4-2, IEC801-2 Conducted immunity EN61000-4-2 Transient response 4 A/100 s 3.0% deviation (See Note 2) GENERAL SPECIFICATIONS Overshoot Nominal output at turn-on 2.0% max.
