1/2/3-Phase Quick-PWM
IMVP-6.5 VID Controllers
General Description
The MAX17030/MAX17036 are 3/2-phase interleaved
Quick-PWM™ step-down VID power-supply controllers
for IMVP-6.5 notebook CPUs. Two integrated drivers and
the option to drive a third phase using an external driver
such as the MAX8791 allow for a flexible 3/2-phase con-
figuration depending on the CPU being supported.
True out-of-phase operation reduces input ripple-current
requirements and output-voltage ripple while easing
component selection and layout difficulties. The Quick-
PWM control provides instantaneous response to fast
load-current steps. Active voltage positioning reduces
power dissipation and bulk output capacitance require-
ments and allows ideal positioning compensation for tan-
talum, polymer, or ceramic bulk output capacitors.
The MAX17030/MAX17036 are intended for bucking
down the battery directly to create the core voltage.
The single-stage conversion method allows this device
to directly step down high-voltage batteries for the
highest possible efficiency.
A slew-rate controller allows controlled transitions
between VID codes. A thermistor-based temperature
sensor provides programmable thermal protection. An
output current monitor provides an analog current out-
put proportional to the sum of the inductor currents,
which in steady state is the same as the current con-
sumed by the CPU.

Note 1: Absolute Maximum Ratings valid using 20MHz bandwidth limit.
Note 2: SHDN might be forced to 12V for the purpose of debugging prototype breadboards using the no-fault test mode. Internal
BST switches are disabled as well. Use external BST diodes when SHDN is forced to 12V.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
