Dual-Output, 3-/2-/1-Phase + 2-/1-Phase

Quick-PWM Controllers for VR12/IMVP7

General Description

Features

S Intel VR12/IMVP-7-Compliant Serial Interface

The MAX17411/MAX17511/MAX17511C/MAX17511N/

MAX17511T are dual-output, step-down, constant on-time

Quick-PWMK controllers for VR12/IMVP-7 CPU core sup-

plies. The controllers consist of two high-current switching

power supplies for CPU and GFX cores. The CPU regulator

(regulator A) is a three-phase constant on-time architecture.

The GFX regulator (regulator B) is also constant on-time

architecture. The MAX17411 supports 2-phase operation

and the MAX17511/MAX17511C/MAX17511N/MAX17511T

support 1-phase operation. The MAX17411/MAX17511/

MAX17511C/MAX17511N/MAX17511T include two internal

drivers on regulator A and one internal driver on regula-

tor B. External drivers such as the MAX17491 enable the

additional phases.

OUT

S Active Voltage Positioning with Programmable

Both regulator A and regulator B include output voltage

sensing and accurate load-line gain. Switching frequen-

cies are programmable from 200kHz to 600kHz per

phase. Output overvoltage protection (OVP, MAX17411/

MAX17511/MAX17511C/MAX17511N), undervoltage pro-

tection (UVP), and thermal protection ensure effective and

reliable operation. When any of these protection features

detect a fault, the controller shuts down both outputs.

S Accurate Lossless Current Balance

S Accurate Droop and Current Limit

S Remote Output and Ground Sense

S Power-Good Window Comparators (POKA and

POKB)

The multiphase regulators include transient-phase over-

lap and active overshoot suppression, which speed up

the response time and reduce the total output capaci-

tance. The CPU and GFX outputs are controlled inde-

pendently by writing the appropriate data into a function-

mapped register file. VID code transitions and soft-start

are enabled with a precision slew-rate control circuit. The

SVID interface also allows each regulator to be individu-

ally set into a low-power, single-phase, pulse-skipping

state to optimize efficiency. The MAX17411 is available in

a 48-pin, 6mm x 6mm, TQFN package. The MAX17511/

MAX17511C/MAX17511N/MAX17511T are available in a

40-pin, 5mm O5mm, TQFN lead-free package.
