LTC3617

Demonstration circuit 1707 is a high efficiency monolithic step-down DC/DC switching regulator designed for double-data-rate (DDR) memory termination in computer systems. The VTT output is capable of sourcing and sinking up to 6A with an output voltage equal to one-half the voltage applied to the V_DDQIN terminal or one-half the input supply voltage, selected by a jumper. An additional low current output (VTTR) also equal to one-half the voltage on V_DDQIN can source and sink up to 10mA. Input voltage range is from 2.25V to 5.5V with overvoltage protection for transients exceeding 6.5V.
