MAX8770 - (MAX8770 - MAX8772) PWM Controller

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.

Key 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 (.

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 www.DataSheet4U.com compensation for tantalum, polymer, or ceramic bulk output capacitors.
