Hybrid Controller 48-Pin VFQFPN Tray

L6717A 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 over-all cost.I²C interface is provided to manage offset for CORE section, switching frequency and dynamic phase management saving in component count and space 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 load-transient response minimizing the output capacitor and reducing the total BOM cost.Fast protection against load overcurrent is provided for both the sections. Feedback disconnection protection prevents from damaging the load in case of misconnections in the system board. L6717A is available in VFQFPN48 package.
