Power circuit terminates DDR DRAMs


Posted on Jan 17, 2013

The circuit of Figure 1 provides the termination voltage for both 1.8 and 2.5V memory systems and delivers output current as high as 6A. IC1 includes a step-down controller and two linear-regulator controllers and operates with input voltages of 4.5 to 28V.



IC1`s fixed-frequency, 200-kHz PWM controller maintains the output voltage by sourcing and sinking current. Maximum sink current equals the maximum source current, though the sink current has no current limiting. When sinking current, the device retu
