MAX8772 - (MAX8770 - MAX8772) PWM Controller

This page provides the datasheet information for the MAX8772, a member of the MAX8770 (MAX8770 - MAX8772) PWM Controller family.

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.

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 (.
