ADP3211A Overview
ADP3211, ADP3211A 7-Bit, Programmable, Single-Phase, Synchronous Buck Controller The ADP3211 is a highly efficient, single−phase, synchronous buck switching regulator controller. With its integrated driver, the ADP3211 is optimized for converting the notebook battery voltage to the supply voltage required by high performance Intel chipsets. An internal 7−bit DAC is used to read a VID code directly from the chip−set...
