VID Controllers Handle IMVP-6.5 CPUs

The MAX17030 and MAX17036 three-/two-phase step-down VID power-supply controllers support IMVP-6.5 notebook CPUs. They integrate two drivers to support two-phase standard voltage (SV) cores while an optional external driver configuration supports three-phase extreme edition (XE) cores. The three phases operate 120° out of phase to minimize input/output filter requirements, improve efficiency, and reduce EMI. Current-sense resistors and low-offset amplifiers maintain current balance across the three phases. The MAX17036 includes an additional transient-suppression feature that reduces the soar/sag voltage. Available in 40-pin, 5 mm x 5 mm TQFN packages, prices start at $5.46 each/1,000.
