DC/DC power supply has electronic circuits that convert one DC voltage level to another. These can be used to provide regulated, unregulated, standard, high isolation or extra wide input voltage for different applications. They can also cater to the high voltage power supply required for your needs.
Modern DC/DC Power Supply: Benefits
Unlike traditional systems, modern power supplies do not need enormous energy to produce the desired output. They are sophisticated devices that deliver enhanced outputs from low voltage or energy. They can even run on a battery and can have multiple modes of input. A modern DC/DC power supply does not have cables, has a compact design, and is compliant with the latest standards with certification of safety and compliance. It also eliminates the need for unnecessary wires as they can be directly connected to the equipment. They function silently, can be installed or shifted easily and can be compatible with a range of equipment. They are also highly efficient and do not produce much heat. These may be custom designed or designed to fit small form factor boards to save space.
DC/DC Power Supply Converters: Tips to Consider Before Purchase
Here are some points to consider before buying converters:
1. Input and output voltage: If you are looking for voltage step up, opt for a boost or buck-boost converter; for voltage step down, get a buck or buck-boost converter. For negative output voltage, an inverting topology is the best option. If you’re getting a DC/DC converter for automotive applications, ensure that it will be able to withstand load-dump, cold-crank and varying temperature conditions (from -40 degrees to +125 degrees Celsius).
2. Ensure that the output voltage will stay within the specifications, irrespective of the load. It should not overshoot the maximum value or undershoot the minimum when the load changes quickly from one extreme to the other.
3. You can opt for those with either Pulse-Width Modulation (PWM) or Pulse-Frequency Modulation (PFM) control schemes. While PWM is used in applications where switching noise may affect other processes, PFM is used in applications that require high efficiency at small loads and low quiescent current.
