This converter is equipped with an integrated shutdown pin, output voltage trim, and thermal protection to guarantee the long lifetime of the application.

The REC3-4815SRWZ/H4/C/SMD DC-DC converter is an application aimed at reducing the cost and complexity of industrial control system inverters. The converter includes an input voltage rating of 36-75V and a maximized switching frequency of 400KHz. It offers a maximum output of 18W and features low EMI capability with easy current limiting. Its high-density package ensures the converter is compact yet reliable.

The working principle of the REC3-4815SRWZ/H4/C/SMD DC-DC converter uses a combination of two stages of switching and frequency control to achieve the desired output power, voltage and current. The first switching stage consists of a fixed-frequency full-bridge power converter, which is driven by the internal oscillator. It converts the input voltage to a variable-width pulse-width-modulated (PWM) signal. This PWM signal is then passed through an inductor and diode to the second stage, a high-frequency (400KHz) variable pulse-width-modulated (VPWM) converter. This second stage of the converter then drives a MOSFET to generate the required output voltage and current.

The REC3-4815SRWZ/H4/C/SMD DC-DC converter is an incredibly cost-effective solution for a wide range of industrial control systems. The integrated protection circuits ensure the long lifetime of the application, while its high-density package allows for a compact design. Moreover, its high efficiency conversion and low-noise operation protect the electronics from high-frequency noise, radio-frequency interference and ground loops. Overall, the REC3-4815SRWZ/H4/C/SMD is an excellent choice for any designer looking for high performance and reliability for their industrial control systems.
