MAX1988 Datasheet (max1987 / Max1988) Quick-pwm Controllers

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-2559; Rev 0; 7/02 PRELIMINARY Dual-Phase, Quick-PWM Controllers for IMVP-IV CPU Core Power Supplies CONFIDENTIAL INFORMATION—RESTRICTED TO INTEL IMVP LICENSEES.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MAX1987/MAX1988 are dual-phase, Quick-PWM™, step-down controllers for IMVP-IV™ CPU core supplies.

Dual-phase operation reduces input ripple current requirements and output voltage ripple, while easing ponent selection and layout difficulties.

The QuickPWM control scheme provides instantaneous response to fast load-current steps.

Key Features

  • power-up sequencing, automatically ramping up to the Intelspecified boot voltage. The MAX1987/MAX1988 also feature independent four-level logic inputs for setting the boot voltage (B0 to B2) and the suspend voltage (S0 to S2). The MAX1987/MAX1988 include output undervoltage protection, thermal protection, and system power-OK (SYSPOK) input. When any of these protection features detect a fault, the controller shuts down. Additionally, the MAX1987 includes overvoltage protection. The MAX1987/MAX19.
