CONFIDENTIAL INFORMATION * RESTRICTED TO INTEL® IMVP-6 LICENSEES 19-3913; Rev 0; 10/05 MAX8770/MAX8771/MAX8772 Dual-Phase, QuickPWM Controlle.
The MAX8770/MAX8771/MAX8772 are 2/1-phase interleaved Quick-PWM™ step-down VID power-supply controllers for notebook CPUs.
Features
* detect a fault, the controller shuts down. A voltage-regulator power-OK (PWRGD) output indicates the output is in regulation. A clock enable (CLKEN) output provides proper system startup sequencing. Additionally, the MAX8771 has a phase-good (PHASEGD) output, and the MAX8770/MAX8772 includes true di
Applications
* either bucking down the battery directly to create the core voltage, or else bucking down the +5V system supply. The singlestage conversion method allows this device to directly step down high-voltage batteries for the highest possible efficiency. Alternatively, 2-stage conversion (stepping down th
