High-Efficiency Hybrid AM2r2 Controller 48-Pin VFQFPN T/R

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.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.The dual-edge asynchronous architecture is optimized by LTB technology allowing fast loadtransient response minimizing the output capacitor and reducing the total BOM cost.Fast protection against load over current is provided for both the sections. Feedback disconnection protection prevents from damaging the load in case of disconnections in the system board.L6717 is available in VFQFPN48 package.
