Dual-Synchronous Buck Controllers for Point-ofLoad, Tracking, and DDR Memory Power Supplies
General Description
The MAX8537/MAX8539 controllers provide a complete power-management solution for both double-data-rate (DDR) and combiner supplies.
The MAX8537 and MAX8539 are configured for out-of-phase and in-phase DDR power-supply operations, respectively, and generate three outputs: the main memory
voltage (VDDQ), the tracking sinking/sourcing termination
voltage (VTT), and the termination reference
voltage (VTTR).
The MAX8538 is configured as a dual out-of-phase controller for pointof-load supplies.
Each buck controller can source or sink u...
