VR11 PWM Controllers Tout High Accuracy

Providing control and switching functions for VR11 CPU core multiphase buck dc/dc converters, the ISL6306 and ISL6307 assume position as the industry's most accurate PWM controllers. Capable of 2-, 3-, 4-, 5-, or 6-phase operation, the controllers specify a system accuracy of ± 0.5% over life, load, line and temperature. Main features include differential remote voltage sensing, adjustable reference-voltage offset, RDS(ON) or DCR current sensing, load-line programming, channel-current balancing, differential current sensing, microprocessor-voltage-identification input, 8-Bit VID input with selectable VR11 code and extended VR10 code at a 6.25 mV step, 0.5V to 1.6V operation, threshold-sensitive enable function, thermal monitoring, programmable temperature compensation, and over-current and over-voltage protection. The ISL6306 is optimized for desktop and embedded systems, while the ISL6307 family is optimized for servers and voltage regulator modules (VRMs). Prices for the ISL6306 (40-lead QFN) and ISL6307 (48-lead QFN) are $2.47 and $3.15 each/1,000, respectively. INTERSIL CORP., Milpitas, CA. (888) 352-6832.
