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.  
Features  
5V at 1A Output  
+36V to +72V Input Voltage Range  
300kHz Switching Frequency  
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.  
Can be Configured for -48V Input and +5V Output  
Selectable Isolated or Nonisolated Operation  
Proven PC Board Layout  
Fully Assembled and Tested Surface-Mount Board  
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.

*With air flow.  
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.
