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.
