Linear DC-DC converters are the simplest converter types, as the voltage here is reduced with a transistor placed between the input and output. The input voltage is reduced by the voltage across the transistor, which causes the output voltage to drop. In a typical circuit of this type, the input and output are connected with a transistor (RVT1 in the picture below). Linear converters reduce output voltage with a resistive load. Common Types of DC-DC Converters Linear & Switching DC-DC Converters As an electronics developer, we also make full use of various DC-to-DC converters when designing power electronics, hardware, and robotics. According to EMR’s Global DC-DC Converter Market report, more than half of them are used in smartphones, but they have other applications as well: from consumer electronics and telecommunication equipment to industrial and medical equipment, factory automation, transportation, robotics, power electronics, etc. Such converters are used in many electronic devices. On top of that, in portable devices, they can raise voltage when the batteries are partially lowered, making power consumption more efficient. It also protects highly-sensitive sub-circuits. These circuits help distribute and manage power properly to provide each power consumer with appropriate voltage or current level. DC-to-DC converters are placed between the power source (an AC-to-DC converter in this case) and voltage consumers. For example, one of the purposes of car DC-DC converters is to regulate the voltage fluctuations in automotive alternators. Additionally, they stabilize voltages, not letting them drop or rise too much. However, if different sub-circuits require different voltages to work properly, one needs to convert the input voltage to a lower or higher level. In most cases, devices use only one power source. Standard electrical functions: Case: Case connection, OVLO: Input overvoltage lockout, UVLO: Input under voltage lockout, OCP: Output over current protection level, OPP: Output over power protection, OVP: Output over voltage protection level, SCP: Output short circuit protection, OTP: Over temperature protection, VIF: Pin for Input Current Ripple Reduction, SYNC: Pin for Synchronisation, TRIM: Pin for adjust ouput voltage, ITRIM: Pin for adjustement ouput current limitation, CC: Pin for capacitor charged signal, CD: Pin for capacitor discharged signal, UVLOadj: Pin for level undervoltage lockout adjust, VREF: Pin for output internal voltage reference, PF: Pin for power fail signal, SENSE: Pin for voltage regulation, REV.What are DC-DC converters and their functions?ĭC-to-DC converters are electromechanical devices or electronic circuits that convert one direct current voltage or current level to another.
