Product overview
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.
