PRODUCT OVERVIEW
The MINMAX MIDER03-HI series is a new range of isolated 3W DC/DC converter modules in DIP-24 package which feature a regulated output and
Ultra-high I/O Isolation voltage rated for 8000VDC with reinforced insulation. A very high common mode transient immunity with 15KV/μs qualifies these
product for IGBT driver applications. Further features include short circuit protection and no min. load requirement and EN55022 class A compliant as well.
There are 15 Models available for 5, 12, and 24VDC input. These converters offer a cost-effective solution for wind turbine, solar panel, transporation
systems, industrial control equipments and some IGBT driver applications where a very high I/O-isolation is required.

Input reflected-ripple current is measured with a inductor Lin (4.7μH) and Cin (220μF, ESR < 1.0Ω at 100 KHz) to simulate source impedance.
Capacitor Cin, offsets possible battery impedance.
Current ripple is measured at the input terminals of the module, measurement bandwidth is 0-500 KHz.

Technical Notes
Maximum Capacitive Load
The MIDER03-HI series has limitation of maximum connected capacitance at the output. The power module may be operated in current limiting mode during start-up,
affecting the ramp-up and the startup time. For optimum performance we recommend 220μF maximum capacitive load for dual outputs and 470μF capacitive load
for single outputs. The maximum capacitance can be found in the data sheet.
Input Source Impedance
The power module should be connected to a low ac-impedance input source. Highly inductive source impedances can affect the stability of the power module.
In applications where power is supplied over long lines and output loading is high, it may be necessary to use a capacitor at the input to ensure startup.
Capacitor mounted close to the power module helps ensure stability of the unit, it is recommended to use a good quality low Equivalent Series Resistance (ESR <
1.0Ω at 100 KHz) capacitor of a 4.7μF for the 5V input devices and a 2.2μF for the 12V and 24V devices.

Output Ripple Reduction
A good quality low ESR capacitor placed as close as practicable across the load will give the best ripple and noise performance. To reduce output ripple, it is
recommended to use 1.5μF capacitors at the output.

Thermal Considerations
Many conditions affect the thermal performance of the power module, such as orientation, airflow over the module and board spacing. To avoid exceeding the
maximum temperature rating of the components inside the power module, the case temperature must be kept below 95℃. The derating curves are determined from
measurements obtained in a test setup.
