Synchronous Buck Controller
The APD3212/NCP3218/NCP3218G is a highly efficient,
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.
The APD3212/NCP3218/NCP3218G uses a multimode architecture
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
