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, MAX8772 are intended for two different notebook CPU core applications: either bucking down the battery directly to create the core voltage, or else bucking down the +5V system supply. The singlestage convers.
