Fairchild Intros FAN6555 Switching Regulator

Fairchild Semiconductor International (San Jose, CA) announced the FAN6555, a low-cost, fully integrated switching regulator designed specifically to handle the termination requirements of double data rate (DDR) memory arrays. 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 termination voltage, regulated to ±3 percent over changing load conditions.

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 also includes several important built-in functions, including a buffered V^REF output for cascaded bus systems, shutdown control for standby mode and thermal shutdown protection against output overloads. The device is designed to operate over a 0 to 70 degrees C temperature range at full load without an external heatsink. The FAN6555 is available in a 16-pin SOIC package.

Samples are available now. Prices are $1.79 for 1,000-piece quantities with delivery in seven to eight weeks ARO.
