DC/DC convertor chipset meets latest Intel specs

The ADP3205 multiphase core controller and the ADP3415 dual MOSFET driver form the first three-phase controller/driver chipset that is fully compliant with IMVP-IV specifications.

The ADP3205 multiphase core controller and its previously introduced ADP3415 dual mosfet driver form the first three-phase controller/driver chipset that is fully compliant with the Intel Mobile Voltage Positioning (IMVP)-IV specifications.

The IMVP specifications are designed to maximise the operating time of notebook computers by carefully minimising the CPU's core voltage and frequency, thus scaling its performance to meet the demands of the system.

Computer OEMs can now use the ADP3205 and ADP3415 to build a dedicated triple-phase core controller with balanced current sharing and superior transient response.

A key feature of the ADP3205 is the pin-selectable one-, two- or three-phase operation.

Operating out of phase, the devices efficiently drive the power mosfet switches of a nonisolated synchronous buck power convertor topology with minimised ripple.

The ADP3205 also includes adaptive noise blanking for high speed and easy board layout, as well as highly redundant over- and undervoltage protection.

These features make the ADP3205 an attractive solution for mobile voltage regulator designers working with computer manufacturers to optimise the performance of their latest Intel CPUs code-named Banias.

The ADP3205 is focused on the thin, light and ultra-portable notebook PCs for maximum operating time and highest performance.

The ADP3205 is packaged in a 40-pin 6 x 6mm chip scale package specified for operation over the industrial temperature range of 0 to +100C.

The ADP3205 is priced at $2.40 per unit in 10,000-piece quantities and samples are available now from stock.
