Tracking, Sinking and Sourcing, Synchronous Buck Controller for DDR Memory and Termination Supplies
General Description
The MAX1917 provides a plete power-management solution for DDR memory. It contains a synchronous buck controller and an amplifier to generate 1/2VDDR voltage for VTT and VTTR. The VTT and VTTR voltages are maintained within 1% of 1/2VDDR. The controller operates in synchronous rectification mode to ensure balanced current sourcing and sinking capability of up to 25A. With a shutdown current of less than 5µA, the MAX1917 is the best choice for low-power notebook applications, as well as servers and desktop puters. An all N-FET design optimizes...
