ADP3211A, ADP3211 Datasheet - ON Semiconductor

ADP3211A Synchronous Buck Controller

Pin No. Mnemonic Description 1 PWRGD Power *Good Output. Open *drain output. A low logic state .

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 or the CPU and to set the GMCH render voltage or the CPU .
