Product Details

DDR Memory Power Supply: 5Vin, 1.25V@+/-6A Vtt (2.5V external reference)

The LTC3831 is a high power, high efficiency switching regulator controller designed for DDR memory termination.The LTC3831 generates an output voltage equal to 1/2 of an external supply or reference voltage. The LTC3831 uses a synchronous switching architecture with N-channel MOSFETs. Additionally, the chip senses output current through the drain-source resistance of the upper N-channel FET, providing an adjustable current limit without a current sense resistor.
