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 proportional 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 specifications. The
MAX8796/MAX17401 are available in a 32 -pin TQFN package. The MAX8797 is available in a 28-pin TQFN
package.

2. Didn't Find What You Need? Ask our applications engineers. Expert assistance in finding parts, usually within one business day.
3. Part number suffixes: T or T&R = tape and reel; + = RoHS/lead-free; # = RoHS/lead-exempt; -D = drypack; -U/+U on DS parts = cut tape. More:
See Full Data Sheet or Maxim Product Naming Conventions.
4. * Some packages have variations, listed on the drawing. "PkgCode/Variation" tells which variation the product uses. Note that "+", "#", " -" in the part
number suffix describes RoHS status. Package drawings may show a different suffix character.
