DESCRIPTION

· The L6758A is a dual controller designed for Intel® VR12 processors, featuring programmable parameters via dedicated pin-strapping.

· It supports two-to-four phase programmable operation for multi-phase sections and a single-phase with independent control loops.

· The device incorporates second-generation LTB Technology for fast load transient response and optimized output filter composition.

· It ensures efficient power state transitions with VFDE, programmable DPM, and GDC, maintaining high efficiency across all loading conditions.

· The L6758A provides robust protection against load overcurrent, under/overvoltage, and feedback disconnections.

· Available in a VFQFPN48 6x6 mm package.

FEATURES

· Compliant with VR12 and 25 MHz SVID bus rev 1.5, supporting serialVID with programmable IMAX, TMAX, VBOOT, and ADDRESS.

· Dual controller: two-to-four phase for core and one phase for graphics (GFX) or system agent (VSA).

· Single NTC design for thermal compensation in TM, LL, and IMON sections.

· Features VFDE and GDC for gate drive control to optimize efficiency.

· Includes DPM for dynamic phase management and dual remote sense.

· Offers 0.5% output voltage accuracy and fully-differential current sense across DCR.

· Supports AVP for adaptive voltage positioning and dual independent adjustable oscillators.

· Equipped with dual current monitors and pre-biased output management.

· Operates with a 5 V supply and 12 V monitor, providing average and per-phase OC protection.

· Includes OV, UV, and FB disconnection protection, along with dual VR_RDY signals.

APPLICATIONS

· High-current VRM / VRD for desktops, servers, workstations, and next-generation CPUs.
