L6759D 3+1 dual controller for VR12 with PMBus

The L6759D is a dual controller designed to power Intel’s VR12 processor memories: all required parameters are programmable through dedicated pin-strapping and PMBus interface.

The device features 3-phase programmable operation for the multi-phase section and a single-phase with independent control loops. Single-phase (VTT) reference is always tracking multi-phases (VDDQ) scaled by a factor of 2.

The L6759D supports power state transitions featuring VFDE, programmable DPM and GDC maintaining the best efficiency over all loading conditions without compromising transient response.

The device assures fast and independent protection against load overcurrent, under/overvoltage and feedback disconnections.

The device is available in a VFQFPN48 6x6 mm package
