Single-Phase Step Down Controller powers NVIDIA® GPUs.
Press Release Summary:
Supplied in 4 x 4 mm package, MAX17409 offers active voltage positioning that lowers output voltage in response to load current and subsequently reduces output capacitance requirements and power dissipation. Load current is sensed at MAX17409's output, minimizing noise sensitivity, and can be sensed using current-sense resistor or DC resistance of inductor. Along with 200-600 kHz adjustable switching frequency, features include overvoltage, undervoltage, and thermal-fault protection.
Original Press Release:
Single-Phase Quick-PWM(TM) Controller for NVIDIA GPUs
Single-phase step-down controller designed specifically for NVIDIA GPUs.
SUNNYVALE, CA-September 14, 2009-Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX17409, a single-phase step-down controller for powering NVIDIA® GPUs. Its active voltage positioning dynamically lowers the output voltage in response to the load current, reducing output capacitance requirements and power dissipation. The load current is sensed at the MAX17409's output to minimize noise sensitivity, and can be sensed using a current-sense resistor or the DC resistance of the inductor. The MAX17409 is well suited for NVIDIA GPU core supplies, notebooks/desktops/servers, or as a general voltage-positioned step-down converter.
The switching frequency is adjustable from 200kHz to 600kHz, allowing designers to optimize for efficiency or component cost/size. This device also features overvoltage, undervoltage, and thermal-fault protection circuitry.
The MAX17409 is available in a space-saving, 4mm x 4mm, 28-pin TQFN package with an exposed backside pad. It is fully specified over the -40°C to +105°C temperature range. Prices start at $4.36 (1000-up, FOB USA).
