Overview
19-2335; Rev 1; 6/02
Tracking, Sinking and Sourcing, Synchronous Buck Controller for DDR Memory and Termination Supplies
General Description
The MAX1917 provides a complete 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 computers.
An all N-FET design optimizes eff...
