1-Phase Quick-PWM
Intel IMVP-6/GMCH Controller
General Description
The MAX8796/MAX8797/MAX17401 are 1-phase Quick-
PWM™ step-down VID power-supply controllers for
Intel notebook CPUs and graphics. The Quick-PWM
control provides instantaneous response to fast load
current steps. Active voltage positioning reduces power
dissipation and bulk output capacitance requirements
and allows ideal positioning compensation for tantalum,
polymer, or ceramic bulk output capacitors.
The MAX8796/MAX8797/MAX17401 are intended for
two different notebook CPU/GPU core applications:
either bucking down the battery directly to create the
core voltage, or else bucking down the +5V system
supply. The single-stage conversion method allows this
device to directly step down high-voltage batteries for
the highest possible efficiency. Alternatively, 2-stage
conversion (stepping down the +5V system supply
instead of the battery) at higher switching frequency
provides the minimum possible physical size.
A slew-rate controller allows controlled transitions
between VID codes. A thermistor-based temperature
sensor provides programmable thermal protection. A
power monitor provides an analog voltage output pro-
portional to the power consumed by the CPU/GPU.
The MAX8796/MAX17401 implement both the Intel
IMVP-6 CPU core specifications, as well as the Intel
GMCH graphics core specifications. The MAX8797
implements the Intel GMCH graphics core specifica-
tions. The MAX8796/MAX17401 are available in a 32-
pin TQFN package. The MAX8797 is available in a
28-pin TQFN package.
