The MAX17021/MAX17082/MAX17482 are 2/1-phase-interleaved Quick-PWM™ step-down VID power-supply controllers for notebook 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 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. A slew-rate controller allows controlled transitions between VID codes, controlled soft-start and shutdown, and controlled exit from suspend. A thermistor-based temperature sensor provides a programmable thermal-fault output (active-low VRHOT). A current monitor output (IMON) provides an analog current output proportional to the power consumed by the CPU (MAX17082/MAX17482 only). Output undervoltage, overvoltage (MAX17021/MAX17082 only), and thermal protection shut the controller down when any of these faults are detected. A voltage-regulator power-OK (PWRGD) output indicates the output is in regulation. Additionally, the MAX17021/MAX17082/MAX17482 feature true differential current sense and a phase-good (PHASEGD) output that indicates a phase imbalance fault condition. The MAX17021 supports the IMVP-6+ specification while the MAX17082/MAX17482 support the IMVP-6.5 requirements. The MAX17021/MAX17082/MAX17482 are available in a 5mm x 5mm, 40-pin TQFN package.
