ADP3209D
5-Bit, Programmable,
Single-Phase, Synchronous
Buck Controller
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 0.4 V to 1.25 V.
programmable switching frequency that can be optimized for
efficiency depending on the output current requirement. In addition,
the ADP3209D includes a programmable load line slope function to
adjust the output voltage as a function of the load current so that the
core voltage is always optimally positioned for a load transient. The
ADP3209D also provides accurate and reliable current overload
protection and a delayed power−good output. The IC supports
On−The−Fly (OTF) output voltage changes requested by the chipset.
