Industrial Non-Isolated DC-DC Converters - High Voltage

High Voltage, Non-Isolated DC-DC Converters for Industrial Applications

The high input voltage NiQor^® family of DC-DC converters offers unique solutions for converting high‑powered, variable voltages to a wide range of output voltages. The converter is a non-isolated buck‑boost regulator, which employs synchronous rectification to achieve extremely high conversion efficiency. These products are suitable for use in Intermediate Bus Architecture, or to provide a regulated output voltage from a variable voltage source such as a battery. They can be configured to ‘buck’ the input voltage down or ‘boost’ the input voltage up using a single external resistor.
