General Description
The MAX5003 50W forward converter evaluation kit (EV
kit) provides a regulated +5V output voltage at currents
up to 10A, when operated from a +36V to +72V input
voltage range.
This EV kit is fully assembled and tested. The output
voltage is preset to +5V. A single-transistor forward-
converter topology with a reset winding is used for high
output power and high efficiency. The use of an opto-
coupler in the feedback circuit provides full 1500V pri-
mary to secondary galvanic isolation. A bottom-mount-
ed heatsink plate safely dissipates the heat generated
by the power MOSFET and the output diode. The power
supply is designed to fit into a small footprint.
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 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 component debris at high velocity. Operate this
EV kit with care to avoid possible personal injury
