VPX 28V

This application note provides additional information on the features and performance of the 28 V VPX power supplies. Topology, operation, efficiency and compliance to MIL‑STD‑461F, MIL‑STD‑704 and MIL‑STD‑1275 are discussed in detail.

NiQor Introduction Application Note

This application note covers the available features and design considerations of SynQor’s high-voltage, non-isolated DCDC converter product families. Examples included in this application note explain how to select the correct part number for a given requirement and how the unique features in these products can be used to simplify the… Read More

Output Load Current Calculation

This application note provides a simple method to calculate the output load current using the current sense resistor found on SynQor’s open frame DC-DC converters. All equations, turns-ratio and sense resistor values are included for the calculations.

Output Voltage Ripple Measurements

This application note explains the existence of occasional high frequency noise spikes when measuring the output voltage ripple on a SynQor converter and how these spikes are largely a measurement artifact. The paper details how to eliminate this measurement error with the proper test set-up and termination methods.

Paralleling Capabilities of SynQor Rack Mount System

This application note provides an overview of the paralleling capabilities of the SynQor Rack Mount System Products. It provides a table of all SynQor rack mount system products which indicates whether they can be paralleled and the type of paralleling method they use.

Paralleling Capability of SynQor Converter Modules

This describes the various paralleling methods used in SynQor converters. It provides a table of all SynQor power converter products which indicates whether they can be paralleled and the type of paralleling method they use. The table also lists whether external paralleling can be implemented if internal paralleling is not… Read More

Start-Up into Capacitive Loads

This application note describes the start‑up characteristics of SynQor converters starting into loads below, near and above the output capacitance limits on the datasheet.

SynQor Series Operation

This application note describes how to connect isolated DC‑DC converters in series to create non‑standard voltages for the industrial market. Wiring diagrams and design considerations are provided for series operation of multiple DC‑DC converters.

Thermal Relief Study

This application note addresses concerns raised with regards to pin and board heating when high currents (>60A) are driven through thermally relieved plated through hole (PTH) vias. Detailed thermal analysis will show that internal heat generation and resulting temperature rise of the power converter and load board is minimal when… Read More

Explanation of 100V Input Transient Protection

This application note provides an overview of SynQor’s input transient protection features and explains the differences in protection ratings across our DC-DC converter product lines. It also answers some frequently asked questions concerning these features.
