MAX17410

Dual-Phase, Quick-PWM Controller for IMVP6+ CPU Core Power Supplies

Dual-Phase Intel IMVP6+ CPU Controllers for Montevina Platform


Please check latest availability status for a specific part variant.

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 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 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 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 a buffered analog voltage output proportional to the power delivered to the load.

The MAX17410 is available in a 48-pin, 7mm x 7mm TQFN package.
