PWM Regulators comply with IMVP-6.5(TM) specification.
October 14, 2009 -
Suited for Intel-based notebooks, networks, and embedded designs, Models ISL62882/3 support various CPUs using programmable 3-, 2-, or 1-phase operation. Configurable overshoot reduction capabilities provide minimal Vout overshoot, which pre-empts voltage misreadings. Both devices feature phase dropping, diode emulation, adaptive body diode conduction time reduction to optimize light load efficiency, and FB2 to optimize transient response. In addition, ISL62882 provides split LGATE function.

New Multiphase PWM Regulators from Intersil Deliver Optimal Voltage Regulation in Compact Packages for Intel Mobile CPUs
ISL62882/3 Complies with IMVP-6.5(TM) and Features Low Power Dissipation, Optimal Thermal Management with Small Footprint for Use in Notebooks, Networks, Embedded Designs
MILPITAS, CA, September 24, 2009 - Intersil Corporation (NASDAQ Global Select: ISIL), a world leader in the design and manufacture of high-performance analog and mixed-signal semiconductors, today introduced new compact multiphase PWM regulators that comply with the Intel Mobile Voltage Positioning (IMVP-6.5TM) specification.
Intersil's new 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 CapellaŽ platform based on the Ibex Peak-MŽ chipset.
Each new regulator supports various CPUs using programmable 3-phase, 2-phase or 1-phase operation. Configurable overshoot reduction capabilities provide minimal Vout overshoot, which pre-empts 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 1-phase mode. In addition, the ISL62882 provides a split LGATE function that further improves efficiency.
Intersil's Robust Ripple Regulator Enables Optimal PWM Performance
To reduce total output voltage ripple, the converters apply interleaved phases. Each phase carries part of the load current, which optimizes system performance, efficiency and thermal management. The PWM modulator is based on Intersil's Robust Ripple Regulator (R3) technology(TM), which commands variable switching frequency during load transients, achieving faster transient response than traditional modulators. With the same modulator, the switching frequency is reduced at light load, increasing the regulator efficiency.
Pricing and Availability
The ISL62882/3 are available now in compact 40-lead QFN packages, with prices starting at $3.93 each in 1,000-piece units.
