ALD20G48-SL

DC-DC converters are power conversion devices that convert a DC voltage to another DC voltage. A typical application for a DC-DC converter is to take a higher voltage, typically 12-48 volts, and step it down to a lower voltage, typically 1.2 to 5.5 volts. They can also step down to a wide range of voltages, making them useful in a variety of applications.

The ALD20G48-SL is an integrated, off-line switched mode power supply, designed for low components count and high efficiency throughout a wide range of output power. The ALD20G48-SL features an active current limit protection, input filter, soft start and under voltage lockout. It comes in a 2.7 x 3.1” package, with a wide range of output options.

The portability of the ALD20G48-SL makes it ideal for use in a variety of applications. These include computer peripherals, PDAs, notebooks, LCD televisions and monitors, medical equipment, industrial equipment, and telecommunication. The high efficiency of the ALD20G48-SL also makes it suitable for use in automotive and renewable energy applications.

The ALD20G48-SL is a very reliable converter, due to its galvanic isolation of the primary and secondary side, and its further integrated protection features. The converter is also very efficient, with an overall efficiency of over 85%, and lower values possible with certain operating conditions. The ALD20G48-SL also has a wide input voltage range, allowing it to accept from 17-25 VDC.

The working principle of the ALD20G48-SL is quite simple. It consists of an isolated flyback converter based on a TL431 regulator. The primary stage of a converter is the switching section, which is responsible for transferring energy between the input and output. The power transformer is also responsible for transferring energy between the primary and secondary side. The TL431 regulates the switching frequency and amplifies current, allowing for precise voltage control of the output.

Finally, the output protection circuit is responsible for detecting any overcurrent, overvoltage, or overtemperature conditions, and shutting down the converter should these conditions occur. This prevents the converter from operating outside of its rated parameters and minimizes damage to the circuitry and load.

In conclusion, the ALD20G48-SL is a very reliable and efficient DC-DC converter. Its wide range of input voltages, integrated protection features, and high efficiency make it ideal for a variety of applications. Its simple functioning principle makes it easy to set up and maintain, and its well regulated output ensures that any connected device operates within its rated parameters.
