L6713A

2/3 Phase controller with embedded drivers for Intel VR10, VR11

and AMD 6 bit CPUs

General features

■ Load transient boost (LTB) technology™ to

minimize the number of output capacitors

(patent pending)

■ Dual-edge asynchronous PWM

TQFP64 (Exposed Pad)

■ Selectable 2 or 3 phase operation

■ 0.5% Output voltage accuracy

■ 7/8 bit programmable output up to 1.60000V -

Description

Intel VR10.x, VR11 DAC

L6713A implements a two/three phase step-down

controller with 180º/120º phase-shift between

each phase with integrated high current drivers in

a compact 10x10mm body package with exposed

pad.The 2 or 3 phase operation can be easily

selected through PHASE_SEL pin.

■ 6 bit programmable output up to 1.5500V -

AMD 6 bit DAC

■ High current Integrated gate drivers

■ Full differential current sensing across inductor

■ Embedded VRD thermal monitor

■ Differential remote voltage sensing

■ Dynamic VID management

Load Transient Boost (LTB) Technology™ (Patent

Pending) reduces system cost by providing the

fastest response to load transition therefore

requiring less bulk and ceramic output capacitors

to satisfy load transient requirements.

■ Adjustable voltage offset

■ Low-side-less startup

■ Programmable soft start

LTB Technology™ can be disabled and in this

condition the device works as a dual-edge

asynchronous PWM.

■ Programmable over voltage protection

■ Preliminary over voltage protection

■ Programmable over current protection

■ Adjustable switching frequency

■ Output enable

The device embeds selectable DACs: the output

voltage ranges up to 1.60000V (both Intel VR10.x

and VR11 DAC) or up to 1.5500V (AMD 6BIT

DAC) managing D-VID with 0.5% output voltage

accuracy over line and temperature variations.

■ SS_END / PGOOD signal

The controller assures fast protection against load

over current and under / over voltage (in this last

case also before UVLO). In case of over-current

the device turns off all MOSFET and latches the

condition.

■ TQFP64 10x10mm package with exposed pad

Applications

■ High current VRD for desktop CPUs

■ Workstation and server CPU power supply

■ VRM modules

System Thermal Monitor is also provided allowing

system protection from over-temperature

conditions.
