MAX1988 - (MAX1987 / MAX1988) Quick-PWM Controllers

Download the MAX1988 datasheet PDF. This datasheet also covers the MAX1987 variant, as both devices belong to the same (max1987 / max1988) quick-pwm controllers family and are provided as variant models within a single manufacturer datasheet.

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 component selection and layout difficulties.

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.

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 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 component selection and layout difficulties. The QuickPWM control scheme provides instantaneous response to fast load-current steps. The MAX1987/MAX1988 include active voltage positioning with adjustable gain and offset, reducing power dissipation and bulk output capacitance requirements.
