STMicroelectronics L6758A
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.| Part No. | L6758A |
