MAX1981A Datasheet | Maxim Integrated

19-2678; Rev 0; 9/02 .. Quick-PWM Master Controllers for VoltagePositioned CPU Core Power Supplies (IMVP-IV) General Description 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 ponent selection and layout difficulties. The MAX1907A/ MAX1981A include active voltage positioning with adjustable gain and offset, reducing power dissipation and bulk output capacitance requirements. The MAX1907A/MAX1981A are intended for two different notebook...
