Description
The L6751C device is a universal digitally controlled dual PWM DC-DC designed to power Intel’s VR12 and AMD SVI processors and memories: all required parameters are programmable through dedicated pin-strapping and PMBus interface. The device features up to 6-phase programmable operation for multi-phase sections and a single-phase with independent control loops. When configured for memory supply, single-phase (VTT) reference is always tracking multi-phase (VDDQ) scaled by a factor of 2. The L6751C 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 WPLGA72 6 x 6 mm
