MAX5003 Evaluation Kit
General Description
The MAX5003 evaluation kit (EV kit) provides a regulat-
ed 5V output voltage up to 1A while operating from a
+36V to +72V input voltage.
The MAX5003 EV kit is a fully assembled and tested
surface-mount printed circuit (PC) board. It comes with
the output voltage set to 5V. This EV kit is configured as
a flyback converter, and can easily be configured for
either isolated or nonisolated operation by selecting the
state of a mechanical switch. Additionally, for systems
in which the input and output ground references are not
at the same potential and for which isolation is not
desired, the user has the option to install a level-shifter
(not supplied) in the controller feedback loop.
WARNING: 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 compo-
nent debris at high velocity. Operate this kit with care to
avoid possible personal injury.
