Synchronous Buck Controller
multi−phase, synchronous buck switching regulator controller. With
its integrated drivers, the APD3212/NCP3218/NCP3218G is
optimized for converting the notebook battery voltage into the core
supply voltage required by high performance Intel processors. An
internal 7−bit DAC is used to read a VID code directly from the
processor and to set the CPU core voltage to a value within the range
of 0.3 V to 1.5 V. The APD3212/NCP3218/NCP3218G is
programmable for 1−, 2−, or 3−phase operation. The output signals
ensure interleaved 2− or 3−phase operation.
run at a programmable switching frequency and optimized for
efficiency depending on the output current requirement. The
APD3212/NCP3218/NCP3218G switches between single− and
multi−phase operation to maximize efficiency with all load conditions.
The chip 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 APD3212/
NCP3218/NCP3218G also provides accurate and reliable short−circuit
protection, adjustable current limiting, and a delayed power−good
output. The IC supports On−The−Fly (OTF) output voltage changes
requested by the CPU.
the extended commercial temperature range of −40°C to
100°C. The ADP3212 is available in a 48−lead QFN 7x7mm
0.5mm pitch package. The NCP3218/NCP3218G is
available in a 48−lead QFN 6x6mm 0.4mm pitch package.
ADP3212/NCP3218 has 1.1 V Vboot Voltage, while
NCP3218G has 987.5 mV Vboot Voltage. Except for the
packages and Vboot Voltages, the APD3212/NCP3218/
NCP3218G are identical. APD3212/NCP3218/NCP3218G
are Halogen−Free, Pb−Free and RoHS compliant.
