MAX17410GTM+

The MAX17410GTM+ from Analog Devices is a versatile 2-/1-phase interleaved Quick-PWM step-down VID power-supply controller specifically designed for notebook IMVP6+ CPUs. Its true out-of-phase operation minimizes input ripple current and output voltage ripple, simplifying component selection and layout.

The Quick-PWM control scheme ensures instantaneous response to rapid load current steps. Active voltage positioning reduces power dissipation and the need for bulk output capacitance, while also allowing for ideal positioning compensation with various capacitor types. This controller is suitable for two primary CPU core applications: directly bucking down the battery for maximum efficiency or bucking down the +5V system supply for a smaller physical size at higher switching frequencies.

Key features include a 7-bit IMVP6+ DAC, dynamic phase selection for optimized efficiency in active and sleep modes, transient phase overlap to reduce output capacitance, and accurate lossless current balance. It also provides remote output and ground sensing, adjustable output slew-rate control, a power-good window comparator, and a power monitor. The device operates within a 4.5V to 26V battery input range and is available in a compact 48-pin, 7mm x 7mm TQFN package.

Applications for the MAX17410GTM+ include IMVP6+ Core Supply, Multiphase CPU Core Supply, and Voltage-Positioned, Step-Down Converters for notebook and desktop computers.
