DC DC Converters - REC3-4805SRW/H2/C/SMD-R Application Field and Working PrincipleDC-DC converters, or DC-DC voltage regulators, are special circuits that convert a source of direct current (DC) from one voltage level to another, using an oscillator circuit to modulate the output by reducing or increasing the voltage. DC-DC converters are typically used in a variety of applications, including photovoltaic applications, automotive power supply systems, consumer electronics, and industrial applications. The REC3-4805SRW/H2/C/SMD-R DC-DC converter is an example of a DC-DC converter that is widely used for a range of applications. The REC3-4805SRW/H2/C/SMD-R is a three-terminal DC-DC converter with a range of 24V to 28V output voltage. It is a buck-type buck-boost converter, designed to operate in a wide input voltage range from 10V up to 28V, with a minimum efficiency of 85%. It is designed to provide a high efficiency solution for small scaled applications. The product is suitable for applications such as computers, TV sets, telecommunication systems and automotive electronics, and is available in a variety of different package sizes.The REC3-4805SRW/H2/C/SMD-R DC-DC converter is an efficient and robust solution for the transportation, industrial, computer, telecom and consumer electronics industries. The efficiency of the product is maximized through the use of advanced technology. The DC-DC converter uses a pulse width modulation (PWM) switching technique to convert the input voltage to the desired output voltage. The device also features an under voltage lock-out (UVLO) between 6V~10V to ensure reliable operation. The operation of the REC3-4805SRW/H2/C/SMD-R DC-DC converter is based on the buck converter principle, also known as the ‘step-down’ switching converter. The REC3-4805SRW/H2/C/SMD-R DC-DC converter is composed of an inductor and a switch and a control circuit. A switch is used to alternately connect and disconnect the input voltage source to the inductor, while the control circuit modulates the switch’s operation. When the switch is in the ‘on’ state, the input voltage is applied to the inductor and a current starts to flow, which in turn creates a magnetic field around the inductor. This magnetic field keeps the current flowing even when the switch is in the ‘off’ state since the collapsing field generates the required current. With the switch in the ‘off’ state, the current stored in the inductor is delivered to the load. This cycle is repeated at a very high frequency, typically between 50kHz to multiple MHz, and the frequency is modulated by the control circuit to obtain the desired output voltage. The output voltage can be controlled by changing the duty cycle and frequency of the switching. The REC3-4805SR
