PRODUCT OVERVIEW
The MINMAX MTQZ50 series is a new gene rati o n of high perf orm ance, convection-cooled 50W DC-DC converters designed specifically for railway
applications. They are available for the popular railway input voltages of either 72(43-101)VDC or 110(66-160)VDC.
The converters conform to railway industry transient standard EN 50155 and complies also with EMC standard EN 50121-3-2.
Advanced circuit topology provides a very high efficiency up to 92% which allows operating temperatures range of -40°C to +85°C. For improved heat
dissipation the modules can be supplied with a heatsink. Further product features include high, reinforced insulation, remote On/Off control, under-voltage
shutdown as well as overload, over voltage, over temperature and short circuit protection.

Technical Notes
Remote On/Off
Positive logic r emote on/ off turns the module on during a logic high voltage on the remot e on/off pin, and off dur ing a logic low. To turn t he power mo dule on and off,
the user mus t sup ply a s witch to control the v oltage between the on/off terminal an d the -Vin terminal. The swi tch c an be an op en collect or or e quivalent. A lo gic low is
0V to 1.2V. A logic high is 3.5V to 12V. The m aximum sink cur rent at th e on/off t ermi nal (Pin 2) during a logic low is -500μA.
Overload Protection
To provi d e hicc up mo d e protect ion in a fault (output overl oad) c ondition, the unit is equipped with internal current limiting circui try and can endure overload for an
unlimi t ed dur at ion.
Overv ol ta ge Pr otec t io n
The o utput overvoltage clamp consists of control circuitry, which is independent of the primary regulation loo p, that monitors the voltage on the output term inals.
The contr ol loop of the clamp has a higher vol tage set point than the prim ary loop. This provides a redundant voltage contr ol that reduces the ris k of out put
overvoltage. The OVP level can b e found in the output data.
Output Ri pple R eduction
A good qual ity low ESR cap acitor placed as close as practicabl e acros s the load wi ll give the best ripple and noi se performance. To reduce output ripple, it is
recommended t o use 4.7μF c apacitors at the output.

Maximum Capaci tive Load
The M TQZ50 series has limi tation of maximum connect ed capacitance at th e outp ut. The power module may be oper ated in curr ent limiting mode during s tart -up,
affecting the ramp-up and the startup time. The maximum c apacitance can be found in the d ata sh eet.
Thermal Considerations
Many condi tions affect the thermal performance of the p ower module, suc h as or ient ation, airflow over the module an d board spaci ng. To avoid exc ee di ng th e
maximum temper ature rating of t he components ins ide the power module, the case temp erature must be kept b elow 105℃. The derati ng cur ves are determined f rom
meas urements obtained i n a test setup.
