MAX17511CGTL+T Power Management Specialized - PMIC Intel IMVP7 CPU Controller

 with non-default boot voltage

Description
The MAX17411/MAX1751 1/MAX1 7511C/MAX17511N/
MAX17511T are dual-output, step-down, constant on-time
Quick- PWMTM 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 MAX1751 1MAX1751 1CMAX17511NMAX17511T
support 1-phase operation. The MAX17411/MAX17511/
MAX1751 1C/MAX1751 1NMAX17511T 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.
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/
MAX17511MAX17511C/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.
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/MAX1751 1NMAX17511T are available in a
40-pin, 5mm x 5mm, TQFN lead-free package.
