Detailed Description
This 100A, quad-phase, buck-regulator design is opti-
mized for a 210kHz frequency and output-voltage set-
Table 1. VID-Programmed Output Voltage
(VRM 10.0)
tings near 1.20V. The output voltage can be digitally set
from 0.8375V to 1.5875V from the VID0 – VID5 pins
(Table 1). At V OUT = 1.20V and V IN = 12V, the inductor
ripple is approximately 35% (LIR = 0.35). The switching
frequency is set by an external resistor R23 (332k ? )
from OSC to ground. The MAX8525 includes a 6-bit
DAC and meets Intel ’ s VRM 10.0 specifications. The kit
features controlled VID voltage transition for dynamic
VID changes and eliminates both undervoltage and
overvoltage overshoot. The PWRGD signal is blanked
during VID code changes to avoid any false fault signal
due to the output voltage change requested by the
CPU. Peak current-mode control provides the fastest
transient response. The proprietary current-sharing
scheme reduces current imbalance between phases to
<5% at full load. The MAX8525 EV kit also includes pro-
grammable no-load offset and output voltage position-
ing to adjust the output voltage as a function of the out-
put current.
The MAX8525 provides cycle-by-cycle current limit to
control the average output current. The EV kit also
offers current-foldback protection under short-circuit
and overload conditions. This feature allows the VRM to
safely operate under a short-circuit condition and to
automatically recover once the short-circuit condition is
removed. Once the output voltage falls below the low-
PWRGD threshold, the foldback-current threshold is set
to half of the current-limit threshold. The foldback pro-
tection is active when the output voltage is below the
PWRGD threshold or the output current is greater than
the current-limit threshold.
