Analog Devices Debuts ADP3205 DC/DC Converter
Analog Devices Inc. (Wilmington, MA) announced its new ADP3205 dc/dc converter and programmable multi-phase controller for mobile CPUs. The ADP3205 is targeted for thin, light and ultra-portable notebook PCs for maximum operating times and high performance. The new ADP3205 multi-phase core controller and its previously introduced ADP3415 dual-MOSFET driver form a three-phase controller/driver chip set that is fully compliant with the Intel Mobile Voltage Positioning (IMVP)-IV specifications, which are designed to maximize the operating time of notebook computers by carefully minimizing the CPU's core voltage and frequency, thus scaling its performance to meet the demands of the system.
A key feature of the ADP3205 is the pin-selectable one-, two- or three-phase operation. Operating out of phase, the devices drive the power MOSFET switches of a non-isolated synchronous buck power converter topology with minimized ripple. The ADP3205 also includes adaptive noise blanking for high speed and easy board layout, as well as redundant over- and under-voltage protection.
The ADP3205 is packaged in a 40-pin, 6mm x 6mm, chip-scale package for operation over the industrial temperature range of
0 to +100 degrees C. The ADP3205 is priced at $2.40 per unit in 10,000-piece quantities and samples are available now from stock.
