DC/DC converters are electrical devices used to convert direct current (DC) from one voltage level to another. The most common applications for DC/DC converters are for powering electronic components from lower voltage sources or for powering multiple components in series from higher voltage sources. The CES48033-30-R is a wide input range, isolated flyback DC/DC converter. It is designed to provide up to 30W of isolated output power without the need for an external transformer.

Applications

The CES48033-30-R is suitable for a wide variety of applications including industrial, automotive, and medical. It can be used in industrial applications for powering sensors, relays, and actuators. It can also be used to provide a 5V output for low voltage microcontroller applications. In automotive applications, it can be used to power accessories such as radios and TVs. In medical applications, it can be used to power medical devices and sensors.

Features

The primary features of the CES48033-30-R converter include its wide input voltage range of 28V – 75V and its ability to provide a 30W output power. It features an adjustable current limit, which enables the user to optimize the power to the required level. Additionally, the converter includes programmable soft-start, frequency foldback, and load disconnect control. The device also provides over temperature (OTP) and short-circuit (SCP) protection.

Working Principle

The working principle of the CES48033-30-R converter involves the conversion of an input DC voltage to an output DC voltage through an isolated flyback configuration. This configuration requires the use of a transformer, and it works by connecting the output of the duty controller to the input of the transformer. This creates a magnetic flux in the transformer, which carries the current. This current is then used to generate the required output voltage. The transformer then isolates the input and output voltage, and allows the output voltage to be regulated by varying the duty cycle.

Conclusion

The CES48033-30-R is an isolated flyback DC/DC converter that is designed to provide up to 30W of output power with wide input voltage range of 28V – 75V. It features adjustable current limit, programmable soft-start, frequency foldback, and load disconnect control as well as over temperature and short circuit protection. The working principle of the converter involves converting an input DC voltage to an output DC voltage through an isolated flyback configuration, which involves the use of a transformer and varying the duty cycle to regulate the output voltage.
