DC-DC converters are a class of electrical power conversion devices. Their purpose is to convert a given DC input voltage or current to a desired DC output voltage or current. They are used in applications where very precise output voltage or current control is required, such as in the power supplies of electronic circuits. The ORHB-C5T03LG is an example of a DC-DC converter used in many applications. This article will discuss the application field and working principle of the ORHB-C5T03LG.

The ORHB-C5T03LG is an isolated flyback converter, meaning that it uses magnetic coupling to isolate and provide electrical isolation between the input and output circuits. The ORHB-C5T03LG is designed to be used in low power converting applications and can provide a regulated output voltage from 0.6V to 5V. It has a wide input voltage range from 4.5V to 33V and can operate from a wide temperature range of -40°C to +85°C. The ORHB-C5T03LG is also designed for high efficiency, with an efficiency up to 96% at 12V input and an efficiency of up to 90% at 24V input. The ORHB-C5T03LG also features excellent regulation accuracy of ±2% with output ripple and noise of 12mV.

The ORHB-C5T03LG can be used in a myriad of applications where low power conversion, accurate regulation, and wide temperature and input voltage range are needed. It is suitable for many consumer, communication, industrial, and automotive applications such as mobile phones, laptop adaptors, plug-in adaptors, industrial power supplies, LED drivers, and solar power applications. The ORHB-C5T03LG can also be used in automotive applications, such as automotive headlight ballasts and vehicle charging systems.

The ORHB-C5T03LG is a non-isolated flyback converter that works by converting an input voltage to an output voltage through a transformer. It uses an inductor connected across the primary winding of the transformer to store energy when the switch is in the on state, and then releases the stored energy when the switch is in the off state. This process is known as ‘flyback’ as the current reverses direction during each switching cycle. When the switch is in the on state, the primary winding of the transformer is in series with the switch and the inductor. As current flows through the inductor, a magnetic field is generated which is coupled to the secondary winding of the transformer. This causes the voltage on the secondary winding to increase, resulting in the output voltage of the converter.

The flyback converter also includes a rectifier and filter capacitor which are used to convert the alternating voltage output of the transformer to a direct voltage. This is known as the rectification process. In addition, the converter also includes an over-voltage protection circuit which is designed to prevent over-voltage conditions from occurring. The over-voltage protection circuit is a safety feature that trips if the output voltage exceeds a certain value.

The ORHB-C5T03LG is an efficient and reliable DC-DC converter that can be used in a wide variety of applications where low power conversion, wide input voltage range, and accurate regulation are needed. Its features, such as high efficiency, excellent regulation accuracy, and wide temperature range make it suitable for many types of applications. The popular ORHB-C5T03LG has become a go-to DC-DC converter for many projects and applications.
