Two-phase DC/DC converter meets Intel's future IMVP spec
26 September 2001
Power Electronics / Power Management
The ADP3203 and ADP3415 is claimed to be the first two-phase controller/drivers chipset on the market that is fully compliant with the next-generation Intel mobile voltage positioning (IMVP) specification, and is also backward-compatible with IMVP-II. This key feature of the Analog Devices' chipset allows OEMs to use the same solution for both Intel mobile Pentium III processors and the forthcoming mobile Pentium 4 processors - without modifying motherboards. Intel's IMVP specification is designed to maximise the operating time of notebook computers by carefully managing the processor's core voltage frequency while maximising CPU performance.
Key features of the ADP3203 include pin-selectable one-phase or two-phase operation, backward compatibility with earlier IMVP-II, and forward compatibility with the latest IMVP specifications. It also includes highly accurate core voltage offsetting, safe detection of the core's VID code at power-up, adaptive noise blanking for speed and stability, and highly redundant overvoltage and undervoltage protection. These features make the ADP3203 an attractive solution for mobile voltage regulator designers working with computer manufacturers to improve notebook computer performance. If used in a two-phase configuration, the chipset delivers up to 40 A to the CORE, with two ADP3415 dual MOSFET drivers. Operating in unison, the devices efficiently drive the power MOSFET switches of a nonisolated synchronous buck power converter topology. Computer OEMs can now build a dedicated dual-phase core converter solution with well-balanced current-sharing and superior transient response.
The ADP3203 is packaged in low-profile 28-pin TSSOP specified for operation between 0°C and +100°C.
