MAX17082GTL+T

The MAX17082GTL+T is a dual-phase, quick-PWM controller for IMVP-6.5 CPU core power supplies in 40 pin TQFN package. The 2/1-phase interleaved Quick-PWM step-down VID power-supply controller with true out of phase operation that reduces input ripple current requirements and output voltage ripple. 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. A current monitor output (IMON) provides an analogue current output proportional to the power consumed by the CPU. It features undervoltage, overvoltage and thermal protection.
