A series of compact multiphase PWM regulators complies with the Intel Mobile Voltage Positioning (IMVP-6.5TM) specification. The ISL62882 and ISL62883 reduce total component cost and implementation footprint for a wide range of Intel-based mobile handsets, notebooks, network systems and embedded designs, including the new Capella platform based on the Ibex Peak-M chipset. Each of these regulators supports various CPUs using programmable three-phase, two-phase or single-phase operation. Configurable overshoot reduction capabilities provide minimal Vout overshoot, which preempts voltage misreadings and the potential for product underperformance or failure. Both devices feature phase dropping, diode emulation, adaptive body diode conduction time reduction to optimize light-load efficiency, and FB2 (full buffering) to optimize transient response and Z(f) in single-phase mode. In addition, the ISL62882 provides a split LGATE function that further improves efficiency. The ISL62882/3 are available now in compact 40-lead QFN packages, with prices starting at $3.93 each in lots of 1000. INTERSIL CORP., Milpitas, CA. (408) 432-8888.
