MAX17080GTL+

Overview

The MAX17080GTL+ is a triple-output, step-down controller designed for AMD’s Serial VID Interface (SVI) CPU and northbridge core supplies. It integrates two high-current synchronous buck converters for CPU cores running 180° out-of-phase to minimize input capacitance, and one 3A internal switch SMPS for the NB core operating at twice the switching frequency. The device features a 4V to 26V battery input range, ±0.5% output accuracy, and a 7-bit onboard DAC providing a 0 to +1.550V adjustment range. It supports programmable switching frequencies from 100kHz to 600kHz and includes integrated drivers for large synchronous rectifier MOSFETs.

Feature Summary

• Dual-output fixed-frequency core supply controller with split or combinable outputs detected at power-up
• Integrated 3A internal switch northbridge SMPS with 100mΩ/50mΩ power switches
• True out-of-phase operation reduces input capacitance while dynamic phase selection optimizes efficiency
• Programmable AC and DC droop with accurate current balance and current limit capabilities

Applications

• AMD SVI CPU core power supplies
• AMD SVI northbridge core power supplies
• Mobile serial VID interface systems
