DC power supply comprises circuits, which convert one level of DC voltage into another. The output voltage level can be used in a great range of applications that require the specific level of input voltage. When needed, the output voltage can also run high voltage electronics very smoothly. The circuit that power supply contains is known as DC DC Converter. A DC DC Converter is a device which performs the ordered task of converting one DC voltage into another level. Probably, both conversions can happen, i.e. from higher to lower and lower to higher. AC to DC and DC to AC converters/inverters contain only two to three major electronic components, whereas DC DC Converter contains more electronic components.
The components that are used in DC DC Converter are: oscillator, transformer and rectifier. The oscillator is the basic part of DC to AC converter, whereas the rectifier is the primary component of AC to DC converter, hence, both is used together with a transformer in DC DC Converter.  The process of DC DC Converter is very intricate, as it first converts DC to AC and then AC to DC to obtain the specific voltage level.
The following are a few tips before purchasing DC DC Converter.
DC DC Converter – Before Purchase Tips
  1. If you are seeking for a voltage step up, then you should pick a boost or buck-boost converter. In case you are looking for step down, so you should choose buck or a buck-boost converter. In need of negative output voltage, picking an inverting topology is the best decision. For purchasing DC DC Converter for automotive applications, make sure that its features include temperature conditions, cold-crank and load-dump.
  2. Before purchasing a DC DC Converter, make sure that the output voltage level will remain same, according to the specifications with respect to the load. When the load changes suddenly from one level to another, then it should not overshoot the maximum voltage or undershoot the minimum voltage.
  3. You are free to choose DC DC Converter with either PFM (Pulse Frequency Modulation) or PWM (Pulse Width Modulation) control schemes. A Pulse Frequency Modulation is used in electronic devices that need low current and high efficiency; load, whereas a Pulse Width Modulation is used in electronic devices that may affect the other processes due to switching noise.
Above are the main useful tips before purchasing a DC DC Converter. These tips will help you to find out an efficient and exact converter that will surely meet your needs. For more info, please visit http://www.chondatech.com/
