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 MIW5000 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.

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.

Overvoltage Protection

The output overvoltage clamp consists of control circuitry,

which is independent of the primary regulation loop, that

monitors the voltage on the output terminals.

The control loop of the clamp has a higher voltage set

point than the primary loop.

This provides a redundant voltage control that reduces the

risk of output overvoltage.

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 12uF for the 12V,

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.

hermal 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.
