General Description
The MAX5069A evaluation kit (EV kit) is a fully assembled
and tested circuit board that contains a high-efficiency,
120W isolated push-pull DC-DC converter. The circuit is
configured for a +12V output voltage and provides up to
10A of output current. The circuit can be powered from
either a +36V to +72V or -36V to -72V DC source, as used
in the telecom/datacom markets, industrial environments,
or in automotive 42V power systems.
High efficiency up to 91% is achieved at 10A while using
two n-channel primary-side MOSFETs switching at up to
90% combined duty cycle. On the secondary-side,
reduced output-voltage ripple and high efficiency is
achieved through full-wave rectification from a center-
tapped planar transformer. Galvanic isolation up to 500V
is achieved by an optocoupler and the planar surface-
mount transformer. The optocoupler helps in providing
isolated secondary-side regulation.
Operation at 500kHz allows the use of small magnetics
and output capacitors. A SYNC input is featured to ease
synchronization to an external clock. The EV kit provides
cycle-by-cycle current-limit protection. Additional steady-
state fault protection is provided by the integrating fault
protection that reduces average dissipated power during
continuous overload conditions. The MAX5069A also has
a programmable input undervoltage lockout (UVLO) for
protection during brownout conditions. The EV kit may be
used to evaluate other versions of the MAX5069.
Warning:
The MAX5069A EV kit is designed to operate
with high voltages. Dangerous voltages are present on
this EV kit and on equipment connected to it. Users who
power up this EV kit or power the sources connected to it
must be careful to follow safety procedures appropriate to
working with high-voltage electrical equipment.
Under severe fault or failure conditions, this EV kit may
dissipate large amounts of power, which could result in
the mechanical ejection of a component or of component
debris at high velocity. Operate this kit with care to avoid
possible personal injury.
