General Description
The MAX8686 current-mode, synchronous PWM stepdown 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 architecture 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 addition, an adjustable soft-start capability
allows for a controlled 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 tracking applications such as DDR memory.
The MAX8686 can be paralleled (up to eight) together in a true multiphase mode
to deliver up to 200A of output current. When operating in this mode, this
device achieves better than 10% current balance between phases at full load.
The MAX8686 supports programmable 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 MAX8686 also features latch overvoltage protection that
turns on the low-side MOSFET when the output voltage exceeds 120% of the
nominal voltage. The MAX8686 is offered in a thermally enhanced 40-pin, 6mm x
6mm TQFN package.
