The MAX17497A evaluation kit (EV kit) demonstrates
the MAX17497A controller IC offline AC-DC flyback
converter design and features an integrated step-down
regulator. The EV kit circuit uses the MAX17497AATE
current-mode fixed-frequency flyback converter in a
16-pin TQFN package with an exposed pad.
The EV kit demonstrates the IC’s cycle-by-cycle current
limit, soft-start, and UVLO features optimized for univer-
sal offline applications (+85V AC to +265V AC). The EV
kit circuit is configured for output voltages of +12V and
+3.3V and provides up to 300mA and 600mA of current
from the respective outputs.
The transformer secondary +12V output is used as the
input source for the IC step-down regulator that provides
+3.3V at VOUT2.
Warning: The 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.
