Single/Multiphase, Step-Down,
DC-DC Converter Delivers Up to 25A Per Phase
General Description
The MAX8686 current-mode, synchronous PWM step-
down regulator with integrated MOSFETs operates from
a 4.5V to 20V input supply and generates an adjustable
output voltage from 0.7V to 5.5V while delivering up to
25A per phase.
The MAX8686 employs a peak current-mode architec-
ture that operates with an adjustable switching frequency
from 300kHz to 1MHz. An adjustable current-limit thresh-
old allows for optimization for different applications with
different load currents. Inductor current sense is
achieved either using an external sense resistor or using
a lossless inductor current-sense scheme. The foldback
and hiccup current limit reduces the power dissipation
during overload or short-circuit conditions and allows for
autorecovery when the fault condition is removed.
The MAX8686 offers the ability to start up monotonically
even when there is a prebias output voltage. In addi-
tion, an adjustable soft-start capability allows for a con-
trolled turn-on. The MAX8686 features an accurate 1%
reference and offers a reference input that allows for a
higher accuracy reference to be used for voltage track-
ing applications such as DDR memory.

achieves better than 10% current balance between
phases at full load. The MAX8686 supports program-
mable phase shedding to improve system efficiency
during light load conditions.
Other features include an enable input and a power-OK
(POK) indicator used for power sequencing. The
