The ADP3205 multiphase core controller from Analog Devices Inc., when combined with the company's ADP3415 dual MOSFET driver, is claimed to form the first 3-phase controller/driver chipset that complies with the Intel Mobile Voltage Positioning (IMVP)-IV specifications.

The IMVP specifications are designed to maximize the operating time of notebook computers by minimizing the CPU's core voltage and frequency, scaling its performance to meet the demands of the system. The ADP3205 is targeted towards Intel's upcoming Banias mobile CPU.

A key feature of the ADP3205 is the pin-selectable 1-, 2-, or 3-phase operation. Operating out of phase, the device is claimed to efficiently drive the power MOSFET switches of a nonisolated synchronous buck power converter topology with minimized ripple.

The 40-pin CSP device also includes an adaptive noise blanking for high speed and easy board layout, as well as highly redundant over and undervoltage protection. The IC is priced at $2.40 per unit in 10,000-piece quantities.
