Analog Devices Intros ADP3204 DC/DC Converter

February 25, 2002 by Jeff Shepard

Analog Devices Inc. (Norwood, MA) announced the ADP3204 controller and the ADP3415 dual-MOSFET driver, which when combined, forms a three-phase controller/driver chipset fully compliant with the IMVP-III specification and backward-compatible with IMVP-II. This feature allows OEMs to use the same core converter solution for both generations.

A key feature of the ADP3204 is the pin-selectable one-, two- or three-phase operation. If used in a three-phase configuration, the chip set delivers up to 50A to the microprocessor core, with three ADP3415 dual-MOSFET drivers. Operating out of phase, the devices efficiently drive the power MOSFET switches of a non-isolated synchronous buck power converter topology with minimized ripple. The ADP3204 also includes adaptive noise blanking for high speed and easy board layout, as well as highly redundant over- and under-voltage protection.

The ADP3204 is packaged a in 32-pin, 5mm x 5mm, chip-scale package, specified for operation over the industrial temperature range between 0 and +100 degrees C. OEM pricing in 10,000-piece quantities is $2.40. Samples and production volumes are available now from stock.
