The MAX5060 evaluation kit (EV kit) provides a +3.3V
adjustable output voltage from a +12V input source. It
delivers up to 20A of output current with a switching fre-
quency of 270kHz and achieves efficiencies up to 93%.
The MAX5060 single-phase, PWM controller provides
high-output-current capability in a compact package
with a minimum number of external components. The
MAX5060 utilizes average current-mode control that
offers accurate current limit and current sharing, and
avoids oversizing the MOSFETs and inductor.
Differential sensing enables accurate control of the out-
put voltage, while adaptive voltage positioning provides
optimum transient response. An internal regulator
enables operation with +4.75V to +5.5V, or +7V to
+28V input-voltage ranges. The high switching frequen-
cy, up to 1.5MHz, allows the use of low inductor and
input capacitor values. This accommodates the use of
PCB-embedded planar magnetics, achieving superior
reliability, current sharing, thermal management, com-
pact size, and low system cost.
The MAX5060 also features a clock input (CLKIN) for
synchronization to an external clock, and a clock output
(CLKOUT) with 180° phase delay to control a second
out-of-phase converter for lower-input-capacitor ripple
current. The MAX5060 also limits the reverse current if
the bus voltage becomes higher than the regulated out-
put voltage. This device is specifically designed to limit
current sinking when multiple power-supply modules
are paralleled. The MAX5060 offers an adjustable
+0.6V to +5.5V (V
