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
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.

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 MIW4100 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.

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
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 < 1.0[ at 100
KHz) capacitor of a 4.7uF for the 24V input devices and a
2.2uF for the 48V 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 3.3uF

capacitors at the output.
