The MAX8775 is a dual step-down, interleaved fixed-frequency, switch-mode power-supply (SMPS) controller with synchronous rectification. The device's configuration is flexible, allowing it to operate as two independent single-phase regulators (separate mode) or as one high-current two-phase regulator (combined mode). It is ideal for GPU cores and I/O power generation in battery-powered systems.
Configured in separate mode, the MAX8775 powers two dynamic voltage rails, one for the GPU core and the other for the I/O power rail. Configured in combined mode, it functions as a two-phase, high-current, single-output GPU core regulator to power the high-performance GPU engines in gaming machines and media center notebooks.
The MAX8775 is available in a 32-pin TQFN package and is specified over the extended-industrial temperature range (-40 degrees Celsius to +85 degrees Celsius). Prices start at $3.45 (1000-up, FOB USA). A MAX8775 evaluation kit is available with recommended external components to reduce design time.
