Description
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 over-
all 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 load-
transient 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.
