Description

The L6718 is a very compact, digitally controlled

and cost effective dual controller designed to

power Intel® VR12 processors. Dedicated

pinstrapping is used to program the main

parameters.

The device features from 2 to 4-phase

programmable operation for the core section

providing 2 embedded drivers. A single-phase

with embedded driver and with independent

control loop is used for GFX.

The L6718 supports power state transitions

featuring VFDE and a programmable DPM,

maintaining the best efficiency over all loading

conditions without compromising transient

response.

Second generation LTB Technology™ allows a

minimal cost output filter providing fast load

transient response. The controller assures fast

and independent protection against load

overcurrent, under/overvoltage and feedback

disconnections.

The device is available in VFQFPN56, 7x7 mm

compact package with exposed pad.
