AMD 2-/3-Output Mobile Serial
VID Controller
General Description
The MAX17080 is a triple-output, step-down, fixed-
frequency controller for AMD’s serial VID interface (SVI)
CPU and northbridge (NB) core supplies. The MAX17080
consists of two high-current SMPSs for the CPU cores
and one 3A 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 3A internal switch SMPS runs at twice the switching
frequency of the core SMPS, reducing the size of the
external components.
The MAX17080 is fully AMD SVI compliant. Output volt-
ages are dynamically changed through a 2-wire SVI,
allowing the SMPSs to be individually programmed to
different voltages. A slew-rate controller allows con-
trolled transitions between VID codes and controlled
soft-start. SVI also allows each SMPS to be individually
set into a low-power pulse-skipping state.
Transient phase repeat improves the response of the
fixed-frequency architecture, reducing the total output
capacitance for the CPU core. A thermistor-based tem-
perature sensor provides a programmable thermal-fault
output ( VRHOT ).
The MAX17080 includes output overvoltage protection
(OVP), undervoltage protection (UVP), and thermal pro-
tection. When any of these protection features detect a
fault, the controller shuts down. True differential current
sensing improves current limit and load-line accuracy.
The MAX17080 has an adjustable switching frequency,
allowing 100kHz to 600kHz operation per core SMPS,
and twice that for the NB SMPS.
