VRD11/VRD10, K8 Rev F 2/3/4-Phase PWM

Controllers with Integrated Dual MOSFET Drivers

General Description

Features

The MAX8809A/MAX8810A synchronous, 2-/3-/4-

phase, step-down, current-mode controllers with inte-

grated 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-volt-

age CPU core power requirements.

♦ Fast Load Tuansient Response

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 dis-

able the IC. True-differential remote output-voltage

sensing enables precise regulation at the load by elimi-

nating the effects of trace impedance in the output and

return paths. A high-accuracy DAC combined with pre-

cision 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 volt-

age-positioning feedback control to achieve high out-

put-voltage accuracy.

(VRHꢂT)

The COMP input allows for either positive or negative

voltage offsets from the VID code voltage. A power-

good signal (VRREADY) is provided for startup

sequencing and fault annunciation. The SS/OVP pin

enables the programming of the soft-start period, and

provides an indication of an overvoltage condition. A

soft-stop feature prevents negative voltage spikes on

the output at turn-off, eliminating the need for an exter-

nal Schottky clamp diode.

The MAX8809A/MAX8810A incorporate a proprietary

“rapid active average” current-mode control scheme for

fast and accurate transient-response performance, as

well as precise load current sharing. Either the inductor

DCR or a resistive current-sensing element is used for

current sensing. When used with DCR sensing, rapid

active current averaging (RA²) eliminates the tolerance

effects of the inductance and associated current-sens-

ing components, providing superior phase current

matching, accurate current limit, and precise load-line.

Applications

Desktop PCs

Servers, Workstations

Desknote and LCD PCs

Voltage-Regulator Modules

Ordering Information

The MAX8809A operates as a single-chip, 2-phase

solution with integrated drivers. It also provides a 3rd-

phase PWM output and easily supports 3-phase design

by adding the MAX8552 high-performance driver. The

MAX8810A enables up to 4-phase designs by adding

the MAX8523 high-performance dual driver for a com-

pact 2-chip solution.
