19-3886; Rev 1; 8/06 EVAALVUAAILTAIOBNLEKIT VRD11/VRD10, K8 Rev F 2/3/4-Phase PWM Controllers with Integrated Dual MOSFET Drivers MAX8809A/MAX8810A General Description The MAX8809A/MAX8810A synchronous, 2-/3-/4phase, step-down, current-mode controllers with integrated dual-phase MOSFET drivers provide flexible solutions that fully comply with Intel® VRD11/VRD10 and AMD K8 Rev F CPU core supplies. The flexible design supplies load currents up to 150A for low-voltage CPU core power requirements. A tri-state SEL input is available to configure the VID logic for either the Intel VRD11/VRD10 or AMD K8 Rev F applications. An enable input (EN) is available to disable the IC.
