GPU core controllers handle wide I/O voltage ratios

Keywords:power supply. GPU controller? I/O voltage wide?


Maxim Integrated Products has developed the MAX17007A/MAX17008 dual, synchronous, step-down, switch-mode power-supply (SMPS) controllers.

The devices utilize Maxim's proprietary, constant on-time, Quick-PWM architecture to support wide input/output voltage ratios, while maintaining a relatively constant switching frequency. This blend of flexibility and performance makes the MAX17007A/MAX17008 suitable for GPU cores and I/O power generation in battery-powered systems. The two SMPS controllers can also be combined to operate as a two-phase, high-current, single-output GPU core regulator for powering the high-performance GPU engines used in gaming machines and media center notebooks.

The MAX17007A/MAX17008 are available in a space-saving, 4mm x 4mm, 28-pin TQFN package, and are fully specified over the -40C to +85C extended-industrial temperature range. Prices start at $3.85 (1000-up, FOB USA). An evaluation kit is available with recommended external components to reduce design time.
