L6717A

High-efficiency hybrid controller

with I

2

C interface and embedded drivers

Datasheet - production data

Features

• Hybrid controller for both PVI and SVI CPUs

G34 compliant

• Dual controller with embedded high current

drivers: 2 phases for CPU CORE + 2 PWM for

ext drivers, 1 phase for NB

• Dynamic phase management (DPM)

• I2C interface to control offset, switching

frequency and PSI_L

• Dual-edge asynchronous architecture with LTB

Technology

®

• PSI management to increase efficiency in light-

load conditions

• Dual overcurrent protection: total and per-

phase compatible with Itdc and IddSpike

• Voltage positioning

• Dual remote sense

• Feedback disconnection protection

• Programmable OV protection

• Oscillator internally fixed at 200 kHz externally

adjustable

• LSLess startup to manage pre-biased output

• VFQFPN48 package

Applications

• Hybrid high-current VRM / VRD for desktop /

server / workstation / IPC CPUs supporting PVI

and SVI interface

• High-density DC-DC converters

Description

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.

I

2

C 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.
