DC DC Converters: REC5-4805DRW/H4/A/M application field and working principle

DC-DC converters are devices that convert and regulate the DC voltage from one level to another level, while also providing isolation from the source and load. The REC5-4805DRW/H4/A/M DC-DC converter module is a monolithic integrated circuit designed for lower input voltage lines such as 3.3V, 5V and 12V. The application and working principle of the REC5-4805DRW/H4/A/M are discussed in this article.

Application field of REC5-4805DRW/H4/A/M

The REC5-4805DRW/H4/A/M is a 4th generation DC/DC converter, designed for a wide range of applications including telecom, industrial, medical, automation, avionics, military and automotive. It is capable of Low Input Voltage operation from 3.3V and 5V rails and provides an adjustable output voltage of 0.8V to 5V at up to 4A of output current. The REC5-4805DRW/H4/A/M is ideal for powering high-density point-of-load (POL) and can be used to easily design switching power supplies for a variety of applications with less component count and smaller overall footprint.

The REC5-4805DRW/H4/A/M makes it easy to design switching power supplies easily, with features such as three data serial ports for external programming and configuration, a temperature monitor and a built-in power good signal for fault monitoring. In addition, the REC5-4805DRW/H4/A/M can be easily set up as a buck converter, boost converter or flyback converter with its two-phase switching architecture.

Working principle of REC5-4805DRW/H4/A/M

The REC5-4805DRW/H4/A/M consists of an inductor, two switches, an external capacitor and an output voltage regulator. The module drives two synchronous MOSFETs for switching operations with the internal oscillator. The pulse width modulation (PWM) feature of the REC5-4805DRW/H4/A/M generates two complementary outputs to control the two MOSFETs. The two switches in the module form a bridge configuration which works in such a way that when one MOSFET is on, the other is off, thus creating an alternate current that is sent to the inductor. The AC current is then converted to DC current before it is sent to the output capacitor. The output voltage regulator inside the module then regulates the output voltage at the desired levels.

The REC5-4805DRW/H4/A/M also has short-circuit and thermal protection features that shut down the power when the module is subjected to excessive current or excessive heat. The module also has an integrated line regulation circuitry that compensates the input voltage variations and ensures output voltage accuracy.

Conclusion

In conclusion, the REC5-4805DRW/H4/A/M is a robust and compact DC/DC converter module that is capable of providing up to 4A of output current and is suitable for a wide range of applications. The module works on a two-phase switching architecture to generate AC current, which is then converted into DC current before the output voltage regulator takes over and regulates the output voltage. The built-in protection and monitoring features ensure efficient and safe operation of the module, making it an ideal choice for designers of power supplies for a range of low voltage applications.
