ADP3211数据手册集成电路（IC）的特殊用途稳压器规格书PDF

描述 Description

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 or the CPU and to set the GMCH render voltage or the CPU core voltage to a value within the range of 0 V to 1.5 V.
