Pentium-class processors offer among the toughest challenges for power-system designers, and the new dual-core chips that meet the Intel VR11 power spec are no exceptions. Intersil is attacking the VR11 market with a controller that can use four to six synchronous-rectified buck channels in parallel. Transient response is a huge problem for such power subsystems. The new Intersil ISL6326 and ISL 6327 controllers rely on the company’s active-pulse-positioning and adaptive-phase-alignment technologies to speed response to load transients, thereby reducing the requirement for external bulk capacitors. A differential amplifier remotely senses voltage, eliminating any potential difference between remote and local grounds, thereby improving regulation and accuracy. Prices for the controllers range from $3.81 to $4.58 (1000).
