Switching Regulator handles double data rate memory.
Share:
Press Release Summary:
Self-contained FAN6555 handles termination requirements of DDR memory arrays. It has high-efficiency MOSFETs capable of handling up to 2A (source and sink) of continuous load current and 3A peak current at termination voltage, regulated to 13% over changing load conditions. Regulator has buffered VREF output for cascaded bus systems, shutdown control for standby mode and thermal shutdown protection against output overloads. Original Press Release:
New Integrated Switching Regulator Handles Special Termination Requirements Of Double Data Rate (DDR) Memory
NEW INTEGRATED SWITCHING REGULATOR HANDLES SPECIAL TERMINATION REQUIREMENTS OF DOUBLE DATA RATE (DDR) MEMORY
San Jose, Calif-October 29, 2001-Fairchild Semiconductor International (NYSE: FCS) announces the FAN6555, a low- cost, fully integrated switching regulator designed specifically to handle the termination requirements of double data rate (DDR) memory arrays. To assure high data rate performance, DDR memory requires the termination voltage (VTT) to be controlled at 50% of the supply voltage (VDDQ). The self-contained FAN6555 includes high-efficiency MOSFETs capable of handling up to 2A (source and sink) of continuous load current, and 3A, peak current at the VTTr termination voltage, regulated to 13% over changing load conditions. The device also includes several important built-in functions, including a buffered VREF output for cascaded bus systems, shutdown control for standby mode and thermal shutdown protection against output overloads.
The fully integrated FAN6555 requires a minimum of external components and greatly simplifies the task of designing memory systems compatible with DDR interface specifications. The device is designed to operate over a 0 to 70°C temperature range at full load without external heat sink. The FAN6555 is available in a 16-pin SOIC package.
