Analog Devices Inc. (Wilmington, MA) announced the ADP3203 and ADP3415, two-phase dc/dc buck controller/drivers chipsets that are fully compliant with the next-generation Intel mobile voltage positioning (IMVP) specification, and is also backward-compatible with IMVP-II.
Key features of the ADP3203 include pin selectable one-phase or two-phase operation, backward compatibility with the 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 redundant over-voltage and under-voltage protection. If used in a two-phase configuration, the chipset delivers up to 40A to the core, with two ADP3415 dual-MOSFET drivers. Operating in unison, the devices efficiently drive the power MOSFET switches of a non-isolated synchronous buck power-converter topology.
The ADP3203 is packaged in a low-profile 28-pin TSSOP, specified for operation over the industrial temperature range between 0 and +100 degrees C. OEM pricing in 10,000-piece quantities is $2.20. Samples and production volumes are available now from stock.
