Hot-selling and scarce MAX8796GTJ+T Controller Voltage Regulator IC Output 32-TQFN spot stock

Product Descriptions

The MAX8796/MAX8797/MAX17401 are 1-phase Quick-PWM™ step-down VID power-supply controllers for Intelnotebook CPUs and graphics . The Quick-PWM control provides instantaneous response to fast load currentsteps . Active voltage positioning reduces power dissipation and bulk output capacitance requirements and allowsideal positioning compensation for tantalum, polymer, or ceramic bulk output capacitors .

The MAX8796/MAX8797/MAX17401 are intended for two different notebook CPU/GPU core applications: eitherbucking down the battery directly to create the core voltage, or else bucking down the +5V system supply . Thesingle-stage conversion method allows this device to directly step down high-voltage batteries for the highestpossible efficiency . Alternatively, 2-stage conversion (stepping down the +5V system supply instead of thebattery) at higher switching frequency provides the minimum possible physical size .

A slew-rate controller allows controlled transitions between VID codes . A thermistor-based temperature sensorprovides programmable thermal protection . A power monitor provides an analog voltage output proportional to thepower consumed by the CPU/GPU .

The MAX8796/MAX17401 implement both the Intel IMVP-6 CPU core specifications, as well as the Intel GMCHgraphics core specifications . The MAX8797 implements the Intel GMCH graphics core specifications . TheMAX8796/MAX17401 are available in a 32-pin TQFN package . The MAX8797 is available in a 28-pin TQFNpackage .
