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
Overcurrent Protection
Input Reflected-Ripple Current Test Setup
To provide protection in a fault (output overload) condition,
the unit is equipped with internal current limiting circuitry and
can endure current limiting for an unlimited duration. At the
point of current-limit inception, the unit shifts from voltage
control to current control. The unit operates normally once the
output current is brought back into its specified range.
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.

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.

Peak-to-Peak Output Noise Measurement Test
Use a Cout 0.47uF ceramic capacitor.
Scope measurement should be made by using a BNC

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.

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 < 1.0[ at 100
kHz) capacitor of a 10uF for the 5V input devices and a 4.7uF
for the 12V input devices and 2.2uF for the 24V and 48V
devices.

Design & Feature Considerations
Maximum Capacitive Load
+
The MIHW1000 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 90° C.
The derating curves were determined from measurements
obtained in an experimental apparatus.
