Application Field and Working Principle of REC3-1212SRW/H4/A DC DC Converters

DC DC converters are popular today in applications that require a power source to change the source or output voltage of a device. They are often used in the electronics industry, especially in personal electronics and small appliances. The REC3-1212SRW/H4/A DC DC converter is specifically designed for use in applications that require converting DC power from a 12V source to a target voltage that ranges from 0.725V to 13.2V. Generally speaking, DC DC converters are widely used in many applications such as in motor control systems, power supplies, medical systems, automotive and telecommunication systems, together with many other industrial applications.The REC3-1212SRW/H4/A DC DC converter is a embedded lithium ion battery charger board used for charging mobile batteries. It has a wide input voltage rage of 10V to 20V, and supports different types of batteries, from 0.725V to 13.2V. It can output a maximum charging current of 1.2A, and offers a wide range of protections like over-voltage, over-temperature, over-charge and over-discharge protections. Its small size and high efficiency makes it ideal for use in a wide range of products, from small embedded systems to larger industrial applications.The REC3-1212SRW/H4/A DC DC converter works on the principle of buck/boost conversion, and it uses a high frequency buck/boost converter circuit as its core. Buck/Boost converters are able to convert the DC input voltage from a higher voltage to a lower voltage, or alternatively from a lower voltage to a higher voltage, depending on the application needs. The circuit can also be configured in such a way that it can step-down or step-up the input voltage to the desired output voltage level. Buck/Boost converters are more efficient than linear voltage regulators, since they don’t suffer from high power loss.When it comes to the REC3-1212SRW/H4/A DC DC converter, the buck/boost circuit works on the principle of switching the input voltage to either a lower or a higher voltage, depending on the application needs. The switching is done using a MOSFET switch, which is controlled by a PWM (Pulse Width Modulation) signal. The control signal is generated by the microcontroller, which is programmed to adjust the duty cycle of the PWM signal according to the desired output voltage level. The higher the duty cycle of the PWM signal (which is only sent when the output voltage is higher than the desired level), the lower the output voltage will be. Similarly, the lower the duty cycle of the PWM signal (which is only sent when the output voltage is lower than the desired level), the higher the output voltage will be.Overall, the REC3-1212SRW/H4/A DC DC converter is a highly efficient embedded lithium ion battery charger board used for charging mobile batteries. It works on the principle of buck/boost conversion, and is able to convert the DC input voltage from a higher voltage to a lower voltage, or vice versa, depending on the application needs. With its wide input voltage range, adjustable power output and efficient power conversion, it is ideal for use in a wide range of industrial applications.
