Input Reflected Ripple Current and Input Ripple Voltage Setup
The module is tested for input reflected ripple current (Irrc). The input ripple voltage is also measured at the pins with and without an
additional 33µF electrolytic capacitor. To reduce either the input ripple current or voltage additional capacitors and/or an inductor may be
added to the input of the converter.

Converter Thermal Consideration
The converter is designed to operate without convective cooling if the de-rating curves are followed. The converter can operate at higher
temperatures and higher output currents if airflow and/or a heatsink are applied. Airflow should be aligned lengthwise to the converter’s
heatsink fins for optimum heat transfer. See Graph 2 for de-rating curves or contact factory for additional thermal information.
