Additional Infomation About Product

L6751B Digitally controlled dual PWM for Intel VR12 and AMD SVI Datasheet production data Features VR12 compliant with 25 MHz SVID bus rev1.5 SerialVID with programmable IMAX, TMAX, VBOOT, ADDRESS AMD SVI compliant Second generation LTB Technology QFN68 8x8 mm Flexible driver/DrMOS support JMode support Description Fully configurable through PMBus The L6751B is a universal digitally controlled dual Dual controller: PWM DC-DC designed to power Intels VR12 and up to 6 phases for CORE and memory AMD SVI processors and memories: all required 1 phase for graphics (GFX), system agent parameters are programmable through dedicated (VSA) or Northbridge (VDDNB) pinstrapping and PMBus interface. Single NTC design for TM, LL and Imon The device features up to 6-phase programmable thermal compensation (for each section) operation for the multi-phase section and a single- VFDE and GDC - gate drive control for phase with independent control loops. When efficiency optimization configured for memory supply, single-phase (VTT) reference is always tracking multi-phases DPM - dynamic phase management (VDDQ) scaled by a factor of 2. The L6751B Dual remote sense 0.5% Vout accuracy supports power state transitions featuring VFDE, Full-differential current sense across DCR programmable DPM and GDC maintaining the best efficiency over all loading conditions without AVP - adaptive voltage positioning compromising transient response. The device Dual independent adjustable oscillator assures fast and independent protection against Dual current monitor load overcurrent, under/overvoltage and feedback disconnections. Pre-biased output management Average and per-phase OC protection The device is available in VFQFPN68 8x8 mm package. OV, UV and FB disconnection protection Dual VR RDY Table 1.
