ADP3209D Synchronous Buck Controller

Pin No 1 Mnemonic FBRTN Description Feedback Return Input/Output. This pin remotely senses the GMCH voltage. It is also used as the ground return for the VID DAC and the voltage error amplifier blocks. 2 FB Voltage Error Amplifier Feedback Input. The inverting input of the voltage error amplifi.

ADP3209D 5-Bit, Programmable, Single-Phase, Synchronous Buck Controller The ADP3209D is a highly efficient, single phase, synchronous buck switching regulator controller. With its integrated drivers, the ADP3209D is optimized for converting the notebook battery voltage to render the supply voltage required by high performance Intel chipsets. An internal 5 bit DAC is used to read a VID code directly from the chipset and to set the GMCH core voltage to a value within the range of .
