製品概要
概要
L6758A is a dual controller designed to power Intel® VR12 processors: all required parameters are programmable through dedicated pinstrapping.
The device features two-to-four phase programmable operation for multi-phase sections and a single-phase with independent control loops. Both sections feature second generation LTB Technology to provide fast load transient response, minimizing and optimizing the output filter composition.
The L6758A supports power state transitions featuring VFDE, programmable DPM and GDC, maintaining the best efficiency over all loading conditions without compromising transient responses. The device assures fast and independent protection against load overcurrent, under/overvoltage and feedback disconnections.
The device is available in VFQFPN48 package.
