DC-DC converters are electronic devices that are used to convert a direct current (DC) power source from one voltage to another voltage. The REC15-483.4SZ/H2 is a type of DC-DC converter commonly used in the field of wireless communications, embedded electronic systems, automotive electronics, and industrial control systems. In this article, we will discuss the application field and working principle of REC15-483.4SZ/H2 DC-DC converters.

The REC15-483.4SZ/H2 is a voltage-controlled DC-DC converter with a constant frequency and high accuracy current control. It can provide a wide range of output voltages, from 0.8V to 8V, which makes it suitable for a wide range of applications. The device has a high input voltage range (8V to 40V) and a wide output current range (0.5A to 8A). It is also capable of operating at temperatures up to 140°C which makes it suitable for use in high temperature environments.

In wireless communications, the REC15-483.4SZ/H2 is used to provide stable power supplies for radio transceivers and base station radios. It is also used to power high power amplifiers and antenna systems which require constant and reliable power. In automotive electronics, the device is used to provide stable voltage supplies for ECUs and other on-board electronics. In industrial control systems, it is used to provide stable power supplies for PLCs, motor control systems, and power supplies for distributed systems.

The working principle of the REC15-483.4SZ/H2 is based on the pulse width modulation (PWM) control. It has a built-in control circuit which regulates the output voltage and current based on the input voltage and feedback signal. The device uses a voltage detection circuit and a PWM driver to regulate the output current and voltage, respectively. The input voltage is divided by a voltage divider circuit to generate a reference voltage to the control circuit. The output voltage is regulated by comparing the reference voltage with the feedback signal. The output current is regulated by comparing the output voltage with the reference voltage.

When the output voltage is higher than the reference voltage, the duty cycle of the PWM signal is decreasing, which reduces the output current and makes the output voltage to the reference voltage again. If the output voltage is lower than the reference voltage, the duty cycle of the PWM signal increases, which increases the output current and changes the output voltage to the reference voltage of the voltage divider circuit. This process is repeated to make the output voltage remain constant.

In short, the REC15-483.4SZ/H2 is a DC-DC converter commonly used in the fields of wireless communications, embedded electronic systems, automotive electronics, and industrial control systems. It is capable of providing a wide range of output voltages, and its high input voltage range and wide output current range make it suitable for a wide range of applications. Moreover, its working principle is based on the PWM control, which allows it to regulate the output voltage and current based on the input voltage and feedback signal.
