DC-DC Converters Terminology Download
This application note defines some of the common terminology used to describe the characteristics and operation of DC/DC converters.
Designing with a Distributed Power Architecture Download
Distributed power architectures (DPA) replace multiple central power sources with a single bulk supply that is converted to the end-use voltages by DC/DC converters located at the point of need. This application note discusses the use of DPA.
EMI Compliance Statement Download
When MIL-STD-461 or other EMI specification is required, an additional power line filter may be needed for the DC/DC converter as well as output and/or protection filters for the other terminals.
EMI Conducted Interference Download
DC/DC converters are natural generators of input narrowband spectral noise currents having components at the fundamental switching frequency and higher order harmonics. The low noise of Interpoint converters can be lowered even further.
Inhibit and Synchronization Download
The inhibit function allows shutdown of the DC/DC converter without interrupting the connection to the input powerbus. The synchronization function allows the converter to be synchronized to an external clock or other devices.
Inrush Current Download
The inrush current for a pulse width modulated (PWM) DC/DC converter is the result of the charging of the input capacitors and/or filter elements and the power converter input current time profile.
Measurement and Filtering of Output Noise Download
In order to determine if an external output filter is needed for a DC/DC converter, an understanding of the nature of output noise and its proper measurement will be helpful. Differential mode (DM) and common mode (CM) noise are discussed.
Mechanical: Mounting, Vibration and Shock Download
This application note addresses how to prevent damage to the DC/DC converter or EMI filter when mounting the product or when the product is subject to vibration and shock.
Quality Assurance and Certification Download
An overview of Interpoint® products Quality Assurance systems, certifications, qualifications, standards and screening tables for DC-DC converters and EMI Input filters.
Thermal Management Download
The internal power dissipation of a DC/DC converter can cause a significant rise in the device case temperature. Thermal Management discusses various options to handle case temperature rise.
Transient Suppression Download
"What is the transient source impedance and what is the volt x second product of the transient?" are two important questions that need at the beginning of a project using DC-DC converters.
