MAX8538 Datasheet Dual-synchronous Buck Controllers

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-3141; Rev 0; 1/04 EVAALVUAAILTAIOBNLEKIT Dual-Synchronous Buck Controllers for Point-ofLoad, Tracking, and DDR Memory Power Supplies MAX8537/MAX8538/MAX8539.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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.
