Test Configurations

Input Reflected-Ripple Current Test Setup

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.

Peak-to-Peak Output Noise Measurement Test

Use a Cout 0.47uF ceramic capacitor.
Scope measurement should be made by using a BNC

socket, measurement bandwidth is 0-20 MHz. Position the
load between 50 mm and 75 mm from the DC/DC Converter.

Design & Feature Considerations

Maximum Capacitive Load

The MIW2100 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.

Overcurrent Protection

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 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
on the input to insure startup.

By using a good quality low Equivalent Series Resistance

(ESR < 1.0[ at 100 kHz) capacitor of 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.

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 that 3.3uF

capacitors are used on 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 90�C.

The derating curves were determined from measurements

obtained in an experimental apparatus.
