L6717  
High-efficiency hybrid AM2r2 controller  
with I2C interface and embedded drivers  
Features  
Hybrid controller for both PVI and SVI CPUs  
Dual controller with 2 embedded high current  
drivers + 2 PWM for external driver for CPU  
CORE and 1 embedded high current driver for  
CPU NB  
Dynamic phase management (DPM)  
VFQFPN48

I C interface to control offset, switching  
frequency and power management options  
Description  
Dual-edge asynchronous architecture with LTB  
®
technology  
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.  
PSI management to increase efficiency in light-  
load conditions  
Dual overcurrent protection: Total and per-  
phase  
Accurate voltage positioning  
Dual remote sense  
2
I C interface allows to manage offset both CORE  
and NB sections, switching frequency and  
dynamic phase management saving in  
component count, space and power consumption.  
Feedback disconnection protection  
Programmable OV protection  
Dynamic phase management automatically  
adjusts phase-count according to CPU load  
optimizing the system efficiency under all load  
conditions.  
Oscillator internally fixed at 200 kHz externally  
adjustable  
LSLess startup to manage pre-biased output  
VFQFPN48 Package  
The dual-edge asynchronous architecture is  
®
optimized by LTB technology allowing fast load-  
Applications  
transient response minimizing the output  
capacitor and reducing the total BOM cost.  
Hybrid high-current VRM / VRD for desktop /  
Server / Workstation / IPC CPUs supporting  
PVI and SVI interface  
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.  
High-density DC / DC converters  
L6717 is available in VFQFPN48 package.
