ADP3209D Overview
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...
