STMicroelectronics L6717
L6717 is a hybrid CPU power supply controller embedding 2 high-current drivers for the CORE section and 1 driver for the NB section - requiring up to 2 external drivers when the CORE section works at 4 phase to optimize the application overall cost. The dual-edge asynchronous architecture is ® optimized by LTB technology allowing fast loadtransient response minimizing the output capacitor and reducing the total BOM cost. L6717 is available in VFQFPN48 package.| Part No. | L6717 |

DESCRIPTION
I2C interface allows to manage offset both CORE and NB sections, switching frequency and dynamic phase management saving in component count, space and power consumption. Dynamic phase management automatically adjusts phase-count according to CPU load optimizing the system efficiency under all load conditions.
