1 / 45 page General Description The MAX17410 is a 2-/1-phase interleaved Quick- PWM™ step-down VID power-supply controller for notebook IMVP6+ CPUs. 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 scheme pro- vides instantaneous response to fast load current steps. Active voltage positioning reduces power dissi- pation and bulk output capacitance requirements and allows ideal positioning compensation for tantalum, polymer, or ceramic bulk output capacitors. The MAX17410 is intended for two different CPU core applications: either bucking down the battery directly to create the core voltage, or bucking down the +5V sys- tem 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 a buffered analog voltage out- put proportional to the power delivered to the load. The MAX17410 is available in a 48-pin, 7mm x 7mm TQFN package.
