19-2678; Rev 0; 9/02 www.DataSheet4U.com Quick-PWM Master Controllers for VoltagePositioned CPU Core Power Supplies (IMVP-IV) General .
The MAX1907A/MAX1981A are single-phase, QuickPWM™ master controllers for IMVP-IV™ CPU core supplies.
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
Applications
* either bucking down the battery directly, or 5V system supply to create the core voltage. The single-stage conversion method allows these devices to directly step down high-voltage batteries for the highest possible efficiency. Alternatively, two-stage conversion (stepping down the 5V system supply
