The MAX17039 is a dual-output, step-down, constant-
on-time controller for VR12/IMVP-7 CPU core supplies.
The controller consists of two high-current-switching
power supplies for the CPU and GPU cores. The CPU
regulator (regulator A) is a three-phase constant-on-time
architecture. The optional 3rd phase is configured with
an external MAX8791 or MAX17491 driver. The second
GPU regulator (regulator B) is also a constant-on-time
architecture with only single phase.
Both regulators A and B include true differential voltage
and current sensing to improve load-line and current-
limit accuracy. Switching frequencies are independently
programmable, allowing 100kHz to 600kHz per phase
operation. Output overvoltage protection (OVP), under-
voltage protection (UVP), and thermal protection ensure
effective and highly reliable operation. When any of
these protection features detect a fault, the controller
shuts down both channels.
Regulator A includes transient-phase overlap, which
speeds up the response time, reducing the total output
capacitance. Regulator A also includes active overshoot
suppression to further reduce the required output decou-
pling capacitance.
Both controllers are fully compliant with Intel’s VR12/
IMVP-7 serial VID communication and control speci-
fications. CPU and GPU outputs are controlled inde-
pendently by writing the appropriate data into a func-
tion-mapped register file. A slew-rate controller allows
controlled transitions between VID codes, controlled
soft-start. The SVID interface also allows each regulator
to be individually set into a low-power pulse-skipping
state. Individual phases can be shut down based on the
processors’ operating conditions to optimize efficiency.
The MAX17039 is available in a lead-free, 56-pin, 7mm x
7mm TQFN package.
