DC-DC Converters Information
DC-DC converters accept DC input and provide regulated and/or isolated DC output in various applications including computer flash memory, telecommunications equipment, and process control systems. DC-DC converters are frequently used on vehicle-mounted systems computer flash memory, telecommunication equipment and process control systems.
DC output is the most important parameter to consider when searching for DC-DC converters. Common outputs converted include:
Choices for nominal DC input for DC-DC converters include:
- 12 VDC
- 24 VDC
- 48 VDC
- 110 VDC
- 280 VDC
Other performance specifications to consider include:
- Output power is measured by the wattage rating, which is the total nominal power output of a converter.
- Line regulation is the percent change in output voltage when VDC input is varied from lowest value to highest value.
- Load regulation is the maximum steady state amount that the output voltage changes as a result of a specified change in load.
- Minimum load is specified for the primary output for converter to meet performance specifications.
- Operating temperature
Common features for DC-DC converters include:
- Constant current supply (CC) designed to provide an output current that stays constant with changes in load impedance.
- Overvoltage protection is internal circuitry that limits or shuts down the voltage output in an overvoltage condition. When present, it is most usually found on the primary output.
- Overcurrent protection is internal circuitry that limits or shuts down the current output in an overcurrent condition.
- Short circuit protection employs techniques to protect the converter in the event of a short circuit on the load may include electronic current limiting and thermal resets with automatic recovery.
- Remote on and off converters have the option to turn the devices on or off remotely.
- Application software included for control or monitoring
Common mounting options include:
- PCB mount
- PC board
- Internal or open frame mount power supplieshave exposed circuitry and components. They aresimply circuit boards to which all of the circuitry and components attach on one side.
- Rack mount come with hardware such as rail guides, flanges, or tabs. Some rack-mounted devices fit in a standard 19" telecommunications rack.
DIN railare standard DIN rail mount. DIN is an acronym for Deutsches Institut für Normung (DIN), a German national organization for standardization.
