Palm Bay, Fla. - Intersil Corporation bills its ISL6568 two-phase PWM controller IC as the industry's smallest all-in-one VID multiphase CPU core regulator. With integrated 3-amp, 5-12 volt MOSFET gate drivers, it claims the highest performance-to-price ratio in the smallest PC board area of any Intel or AMD CPU core voltage regulator available.
A unique feature of the ISL6568 is the use of both (inductor) DC-resistance and MOSFET on-resistance for current-sensing. It achieves load-line voltage positioning (droop) and over-current protection through continuous inductor current-sensing, while on-resistance current-sensing ensures accurate phase-to-phase channel-current balance.
The ISL6568 is available now in standard lead finish and Pb-free, 32-lead 5-by-5 mm QFN packages. The device is rated for operation over the commercial or industrial temperature ranges. Its suggested price is $1.45 each in 10k quantities.
