MAX8809A
Description
The MAX8809A/MAX8810A synchronous, 2-/3-/4phase, step-down, current-mode controllers with integrated dual-phase MOSFET drivers provide flexible solutions that fully ply 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. True-differential remote output-voltage sensing enables precise regulation at the load by eliminating the effects of trace impedance in the output and return paths. A high-accuracy DAC bined with precision current-sense amplifiers and droop control enable the MAX8809A/MAX8810A to meet the most stringent tolerance requirements of new-generation high-current CPUs. These ICs use either integral or voltage-positioning feedback control to achieve high output-voltage accuracy.
