I. Device Description

A. General

The MAX17028 is a 1-phase Quick-PWM™ step-downVID power-supply controller for Intel notebook CPUs. 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 MAX17028 is 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 current monitor provides an analog output current proportional to the processor load current. The MAX17028 implements both the Intel

IMVP-6.5 CPU core specifications (V3P3 = 3.3V), as well as the Intel GMCH graphics core specifications (V3P3 =GND). The 17028 is available in a

32-pin, 5mm x 5mm, TQFN package.
