NCP4208
VR11.1 Digital
Programmable 8-Phase
Synchronous Buck
Converter with I 2 C
Interface
The NCP4208 is an integrated power control IC with an I 2 C interface.

The NCP4208 is a highly efficient, multiphase, synchronous buck
switching regulator controller, which aids design of High Efficiency and
High Density solutions. The NCP4208 can be programmed for 1 ? , 2 ? ,
3 ? , 4 ? , 5 ? , 6 ? , 7 ? or 8 ? phase operation, allowing for the construction of
1 48
QFN 48
CASE 485AJ
up to 8 complementary buck switching stages.
The NCP4208 supports PSI, which is a power state indicator and
can be used to reduce the number of operating phases at light loads.
The I 2 C interface enables digital programming of key system
parameters to optimize system performance and provide feedback to
the system.
The NCP4208 has a built in shunt regulator that allows the part to be

powered from the +12 V system supply through a series resistor. The
NCP4208 is specified over the extended commercial temperature
range of 0 ° C to +85 ° C and is available in a 48 Lead QFN package.
