MAX1981A Quick-PWM Master Controllers

The MAX1907A/MAX1981A are single-phase, QuickPWM™ master controllers for IMVP-IV™ CPU core supplies. Multi-phase operation is achieved using a Quick-PWM slave controller (MAX1980). Multiphase operation reduces input ripple current requirements and output voltage ripple while easing component selecti.

MAX1981A Features

* power-up sequencing, automatically ramping up to the Intel-specified boot voltage. The MAX1907A/MAX1981A feature independent four-level logic inputs for setting the boot voltage (B0

* B2) and the suspend voltage (S0

* S2). The MAX1907A/MAX1981A include output undervoltage protection, the
