DC DC Converters: REC3-2412DRW/H2/C/M/SMD Application Field and Working Principle

DC-DC converters are widely used in all fields and applications, as they help to provide a current or voltage that is required for a certain device. The REC3-2412DRW/H2/C/M/SMD is a DC-DC converter that is commonly used due to its ability to convert from a regulated 12V input voltage to an adjustable output voltage of 1.2V to 24V in 1.2V incremental steps. It offers a wide range of features, such as an internal selectable frequency of 300kHz, 500kHz, and 1.5MHz.The REC3-2412DRW/H2/C/M/SMD regulates the output voltage by using pulse-width modulation (PWM) and can support up to a load of 350mA. The module also features internal soft start, protection from short circuit or over-temperature, under-voltage lock-out (UVLO) and enable control. The application fields that the DC-DC converter is suitable for include automotive applications, portable and consumer electronics, test and measurement equipment, office automation products, mobile devices, DC brushless fans, set-top boxes and home appliances.The principle of the REC3-2412DRW/H2/C/M/SMD DC-DC converter is based on the pulse-width modulation technique. In this setup, the input voltage is converted into a fixed or adjustable frequency rectangular waveform, otherwise known as a PWM waveform. The output voltage is determined by the pulse width ratio of the PWM waveform, which is generated by the on-chip PWM controller IC. The pulse width of the PWM waveform is actively regulated by setting the integrated current sources, resulting in the desired output voltage.The REC3-2412DRW/H2/C/M/SMD is an isolated DC-DC converter that uses isolated magnetic components, which allow for an isolated flyback topology. Isolation is necessary in order to limit the effects of switching noise on the load side of the converter. The transformer that is used in this converter is a coupled inductor, which helps minimize power losses and reduces the overall size of the converter.The REC3-2412DRW/H2/C/M/SMD also features a number of protections to ensure the module operates safely and reliably. These include an integrated soft start circuit, which prevents inrush current during power-up; an over temperature protection, which protects the converter from overheating; and a short-circuit protection, which protects the output from a potential short on the load side of the converter. The DC-DC converter also features an under voltage lock-out (UVLO) feature, which ensures the converter does not start up when insufficient input voltage is present. In conclusion, the REC3-2412DRW/H2/C/M/SMD is a reliable DC-DC converter that offers adjustable output voltage and is suitable for a range of applications in the automotive, portable and consumer electronics, test and measurement, office automation, and home appliance markets. Its principle of operation is based on the pulse-width modulation (PWM) technique and it features a range of protections, such as soft start, over temperature, and short-circuit protection, as well as an under voltage lock-out.
