MAX5015 Evaluation Kit
General Description
The MAX5015 evaluation kit (EV kit) is a fully assembled
and tested circuit board that contains a 50W forward
converter in the industry standard half-brick footprint.
The circuit is configured for a +5.0V output voltage and
provides up to 10A of current. Power for the circuit can
be provided from either a +36V to +72V or -36V to -72V
DC source.
High efficiency of 86% is achieved at 5A using a single
transistor, forward converter topology providing output
power up to 50W. The surface mount transformer pro-
vides galvanic isolation and has a reset winding to
recover magnetic energy. Galvanic isolation up to
1500V is achieved by an optocoupler and surface-
mount transformer.
Operation at 280kHz allows the use of small magnetics
and output capacitors.
Warning:
The MAX5015 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 connect-
ed 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.
