CONFIDENTIAL INFORMATION – RESTRICTED TO INTEL® IMVP-6 LICENSEES 19-3913; Rev 0; 10/05 MAX8770/MAX8771/MAX8772 Dual-Phase, QuickPWM Controller for IMVP-6+ CPU Core Power Supplies General Description The MAX8770/MAX8771/MAX8772 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. The MAX8770/MAX8771/MA [ ... ]
