REC3-2409SRW/H4/C/SMD-R

DC-DC converters are electronic converters that convert one form of direct current (DC) input into a different direct current output voltage. The most common DC-DC converters are step-up (boost), step-down (buck), and inverting (buck-boost) converters. There are many applications for these devices, ranging from consumer electronics and industrial applications to distributed power networks and automotive systems.

The REC3-2409SRW/H4/C/SMD-R is a high-efficiency DC-DC switching step-down (buck) converter with a 3A maximum output current. The device is designed to operate from a wide input voltage range of 4.5V to 36V and provide a regulated fixed output voltage of 5V. This fixed 5V output is adjustable with an external resistor. The device has a wide input voltage range, low noise operation, and high efficiency, making it ideal for a variety of applications such as automotive, consumer, industrial, and medical.

The operating principle of the REC3-2409SRW/H4/C/SMD-R is based on a switch mode topology. The topology consists of an input rectifier, an output rectifier, a main switching transistor, an auxiliary winding, and a control IC. The main switch is used to alternately connect the input voltage to a storage inductor, which will eventually be discharged to the output. The control IC is used to regulate the output voltage by varying the duty cycle of the main switch.

The rectifiers ensure that the input voltage and output voltage are rectified to the DC levels needed for the converter to operate. The auxiliary winding provides a control feedback signal to the control IC on the output voltage. When the output voltage is lower than the reference, the duty cycle of the main switch increases and more current is drawn from the input. The additional current then flows from the input, through the inductor, and into the output, increasing the output voltage until it matches the reference voltage.

The REC3-2409SRW/H4/C/SMD-R is a highly efficient and reliable DC-DC Converter that is suitable for a variety of applications. Its wide input voltage range, low noise operation, and high efficiency make it an ideal choice for applications such as automotive, consumer, industrial and medical.
