MAX17480 datasheet



The MAX17480 is a triple-output, step-down, fixed frequency controller for AMD’s serial VID interface (SVI) CPU and northbridge (NB) core supplies. The MAX17480 consists of two high-current SMPSs for the CPU cores and one 4A internal switch SMPS for the NB core. The two CPU core SMPSs run 180° out-of-phase for true interleaved operation, minimizing input capacitance. The 4A internal switch SMPS runs at twice the switching frequency of the core SMPS, reducing the size of the external components.

The MAX17480 is fully AMD SVI compliant. Output voltages are dynamically changed through a 2-wire SVI,allowing the SMPSs to be individually programmed to different voltages. A slew-rate controller allows controlled transitions between VID codes and controlled soft-start. SVI also allows each SMPS to be individually set into a low-power pulse-skipping state.
