DC-DC converters are widely used in all sorts of electronic products. REC5-2412DRWZ/H2/A is a kind of DC-DC converter. This article will discuss the application field of REC5-2412DRWZ/H2/A and its working principle.

Application Field of REC5-2412DRWZ/H2/A

REC5-2412DRWZ/H2/A is a kind of DC-DC converter applied in power supply systems. It plays an important role in providing precise and reliable voltage no matter how the traffic or power-grid are changing.

The device is a two-phase DC-DC converter with a maximum power of 120W. It provides a high degree of efficiency, extremely low output noise, and superior load regulation characteristics. As a two-phase converter, it can reduce the size of the inductor and output capacitor, while maintaining high power density. REC5-2412DRWZ/H2/A can be widely used in computers, communication equipment, industrial control systems, automobiles, aircraft, and medical equipment.

Working Principle of REC5-2412DRWZ/H2/A

The REC5-2412DRWZ/H2/A is a synchronous rectification buck DC-DC converter with differential sensing, which works through the following steps.

Firstly, the PWM control circuit will compare the voltage feedback signal and the reference voltage, and according to the comparison result, it will determine whether to turn on the MOSFETs. At the same time, the current sense signal is sent to the current limit circuit, forming a loop.

Secondly, when the MOSFETs are turned on, the two inductors in the circuit will produce opposite flux. To ensure that the two inductors will not oppositely affect each other, one of them will be driven by the main chip clock and the other will be driven by the inverted clock, which is out of phase with the main chip clock signal. Thus, the flux generated by the inductor can be added rather than subtracted.

Finally, a fly-back diode is connected to the inductor, providing a path for the current carriers to flow back into the circuit in the opposite direction. When the MOSFET is turned off, the stored energy in the inductor will form a continuous current loop, and flow back to the circuit, forming a negative voltage. Thus, making it possible to convert the main supply voltage into a much lower or higher output voltage.

In conclusion, REC5-2412DRWZ/H2/A is a DC-DC converter that can provide precise and reliable voltage no matter how the traffic or power-grid are changing. Its working principle is explained in the above three steps. The device has a wide range of applications and can be used in computers, communication equipment, industrial control systems, automobiles, aircraft, and medical equipment.
