DC-DC converters are widely used in various electronic systems, from low voltage to high voltage. REC3-4812SRW/H/B/SMD-R, a switching regulator, is one of the most popular DC-DC converters available for commercial applications. This article will discuss its application field and working principle.
The main application of REC3-4812SRW/H/B/SMD-R is to convert a DC input voltage to a higher DC output voltage. It can be configured as either a buck or boost regulator. The input voltage range of the converter is 4.5 to 38V, and its output voltage range is 5.0 to 48V. It also has a wide operating temperature range, from -40C to +85C. The efficiency of the converter can be as high as 92%, making it suitable for high power applications.
The working principle of the REC3-4812SRW/H/B/SMD-R involves a PWM controller and an N-channel MOSFET switch. The controller generates a periodic signal, the duty cycle of which is determined by the input voltage level. The switch is responsible for connecting and disconnecting the input voltage to the output voltage at the required frequency. The input voltage is also regulated by the controller so that it is always within the allowable range.
When the switch is connected to the input voltage, the energy will be stored in the inductor. When the switch is disconnected, the energy stored in the inductor will be transferred to the output voltage. The output voltage is then regulated by the current sense resistor. If there is an overcurrent condition, the current sense resistor will reduce the voltage output of the converter, protecting the device from damage.
The REC3-4812SRW/H/B/SMD-R is a versatile and reliable switching regulator, that is suitable for many industrial applications. With a wide input voltage range and operating temperature range, and its high efficiency, it is an ideal choice for applications requiring DC-DC conversion.
