The LTC®3717 is a synchronous step-down switching regulator controller for double data rate (DDR) and Quad Data Rate TM (QDRTM) memory termination. The controller uses a valley current control architecture to deliver very low duty cycles without requiring a sense resistor. Operating frequency is selected by an external resistor and is pensated for variations in...
