NCP4200
Programmable Multi-Phase
Synchronous Buck
Converter with I 2 C
Interface
The NCP4200 is an integrated power control IC with an I 2 C
interface. It combines a highly efficient, multi ? phase, synchronous
buck switching regulator controller with an I 2 C interface, which
enables digital programming of key system parameters to optimize
system performance and provide feedback to the system.
It uses an internal 8 ? bit DAC to read a Voltage Identification (VID)
code directly from the processor, which is used to set the output
voltage between 0.375 V and 1.6 V.
This device uses a multi ? mode PWM architecture to drive the
logic ? level outputs at a programmable switching frequency that can
be optimized for VR size and efficiency. The NCP4200 can be
programmed to provide 2 ? , 3 ? , or 4 ? phase operation, allowing for the
construction of up to four complementary buck ? switching stages. The

NCP4200 supports PSI, which is a Power Save Mode.
The NCP4200 includes an I 2 C interface which can be used to
program system set points such as voltage offset, load ? line and phase
balance and output voltage. Key system performance data, such as
CPU current, CPU voltage, and power and fault conditions can also be
read back over the I 2 C from the NCP4200.
The NCP4200 operates over the industrial temperature range of
