DC-DC Converters are an important component of many electronics and electrical systems, providing efficient and reliable power conversion from one voltage to another. The REC5-1212DRW/H4/C/SMD is a moveable step-down DC-DC converter module which includes several important features, making it suitable for a wide range of applications. This article will provide a closer look at the REC5-1212DRW/H4/C/SMD, discuss its application field, and its working principle.

The REC5-1212DRW/H4/C/SMD is a moveable step-down DC-DC converter module which comprises integrated MOSFET, inductor, diode, and output capacitors and whose input voltage range is 4.5V to 45V. This module boasts an output voltage of 5V and a maximum output current of 12A, and it has a peak efficiency of 95%. This module is designed for a wide temperature range of -40°C to +125°C, and can withstand transients up to 40V for up to 100ms. Due to its rugged design and high operating temperature, it is ideal for use in military, industrial, automotive, and telecommunications applications.

The REC5-1212DRW/H4/C/SMD’s main function is to convert the input voltage into a lower-voltage output. This is achieved by utilizing a buck regulator topology with an integrated power MOSFET. The MOSFET is driven by a high-frequency, adjustable-frequency, current-mode PWM signal, allowing it to periodically switch on and off rapidly during each cycle of the input voltage. As a result, this causes the output voltage to be lower than the input voltage. Each cycle of the PWM signal is determined by the voltage values on two pins: VCC and GND. The output voltage is then controlled by the potential difference between these two pins.

Besides voltage conversion, each cycle of the PWM signal also causes current to flow in the MOSFET to charge an inductor. The stored energy in the inductor is then released when the PWM signal results in its de-activation. This in turn causes the output capacitors to draw current to provide the stable output voltage. This process continues to repeat itself, providing a consistent output voltage as long as the input voltage is within the rated voltage range.

Due to its high efficiency, high temperature rating, and adjustable output voltage, the REC5-1212DRW/H4/C/SMD is suitable for use in a wide variety of applications, such as military, industrial, automotive, and telecommunications equipment. It can be used in portable devices such as laptops, PDAs, digital cameras, and cellular phones, as well as larger equipment such as industrial robots, medical equipment, LED lighting, and point-of-sale systems.

The REC5-1212DRW/H4/C/SMD DC-DC converter provides a reliable and efficient voltage conversion solution in a wide range of applications. By understanding its working principle and application field, designers and technicians can make an informed choice regarding the best DC-DC converter for their specific needs.
