Notes :
1. Specifications typical at Ta=+25], resistive load, nominal input voltage, rated output current unless otherwise noted.
2. Transient recovery time is measured to within 1% error band for a step change in output load of 75% to 100%.
3. Ripple & Noise measurement bandwidth is 0-20 MHz.
4. These power converters require a minimum output loading to maintain specified regulation.
5. Operation under no-load conditions will not damage these modules; however, they may not meet all specifications listed.
6. All DC/DC converters should be externally fused at the front end for protection.
7. Other input and output voltage may be available, please contact factory.
8. Specifications subject to change without notice.

Test Configurations
Input Source Impedance
Input Reflected-Ripple Current Test Setup
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
on the input to insure startup.
Input reflected-ripple current is measured with a inductor
Lin (4.7uH) and Cin (220uF, ESR < 1.0[ at 100 kHz) to
simulated source impedance.
Capacitor Cin, offsets possible battery impedance.
Current ripple is measured at the input terminals of the
module, measurement bandwidth is 0-500KHz.

(ESR < 1.0[ at 100 kHz) capacitor of a 10uF for the 12V input
devices and a 4.7uF for the 24V input devices and a 2.2uF for
the 48V devices, capacitor mounted close to the power
module helps ensure stability of the unit.

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 that 3.3uF
capacitors are used on output.

Maximum Capacitive Load
The MIHW3000 series has limitation of maximum
connected capacitance on the output.
The power module may operate in current limiting mode
during start-up, affecting the ramp-up and the startup time.
Connect capacitors at the point of load for best
performance.
The maximum capacitance can be found in the data sheet.

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° C.
The derating curves were determined from measurements
obtained in an experimental apparatus.
