DG200-J

When researching AC-DC converters, DG200-J is an acronym used regularly. The device is a monolithic integrated power supply controller. It is widely used in applications that require AC-DC conversion, such as televisions, computers, air conditioners, and many other devices. In simple terms, the device is used to convert the alternating current in a circuit into a direct current.

This integrated controller was developed by Infineon Technologies and it operates within the power rang of 10V and 20V. The range can be easily modified with the addition of an external voltage divider. This version was the first to introduce the protection tester which comes with an under voltage lockout.

The DG200-J is mostly known as a ‘step-down’ converter. This is because it can accept any voltage from zero to input voltage and convert it to any output voltage from zero to the input voltage. This is a crucial feature for any AC-DC converter, as it can reduce the power output from the higher voltage source that has been supplied to a lower voltage level. The output voltage remains controlled throughout the process, allowing it to be used in a higher range of applications.

The internals of the converter acts as a type of bridge. It consists of two diodes, two transistors, and an optocoupler. When the alternating current reaches the entry point of the converter, the two diodes are normally switched on. The current is then passed through the transistors, creating a bridge. The result is the creation of a low frequency, low voltage alternating current.

At the output stage, the optocoupler is used to rectify the current. It converts the alternating current to a direct current. The result is a direct current output that can be easily controlled and regulated.

The benefits of using a DG200-J step-down converter are numerous. As well as reducing the power output from an input voltage level, the device also has an impressive power efficiency. It offers high efficiency by using the Pulse Width Modulation (PWM) method. This ensures that the device can handle wide voltage ranges, while providing a lower power demand. As the converter does not require additional cooling gear, the device remains ultra-reliable.

Overall, the DG200-J converter is an ideal choice for a wide range of AC-DC applications. It is easy to use and setup, highly reliable and efficient, and can handle a wide range of power levels. With its impressive range of features, it is no wonder it is so widely used in AC-DC conversion applications.
