The TEA1753LT/N1,518 is a low cost AC/DC converter module designed for use in applications where an isolated AC input is used. This converter module provides 5A output current with a rated output voltage of 24V, while featuring high efficiency, low ripple and low standby current. There are several features to this device, including thermal protection, remote on/off control, overvoltage protection and soft start. Suitable applications for this device include solar panel charge controllers, electric bicycles and appliances, LED lighting, and battery chargers.

The TEA1753LT/N1,518 AC/DC converter module has a two-stage power conversion design that utilizes a flyback power converter with a boost converter. In the first stage, the AC to DC power conversion is performed by the flyback converter. This design topology uses a high frequency transformer to isolate the input from the output as well as providing regulation of voltage. The flyback converter transforms an AC input voltage to a fixed DC voltage by rectifying, filtering and regulating the input voltage. The second stage is the boost converter, which is used to boost the output voltage up to the desired output voltage. The boost converter is a switching mode power supply with a buck-boost-flyback topology, allowing it to provide a regulated output voltage even when the input voltage is varying. The boost converter also provides isolation between the input and the output, further protecting the device from any potential faults or spikes in the AC line.

The TEA1753LT/N1,518 AC/DC converter module also features a soft start circuit. This circuit limits the inrush current of the device when it is first powered up, preventing spikes in current on the DC output that may effect the performance of the device. The soft start also allows for protection against short circuit and overload conditions, essentially locking out the device when an excessive load is placed on it. As well as providing protectionsa against overload, this device also features overvoltage protection, ensuring that the output voltage is limited to within the specified operating range.

This AC/DC converter module is capable of operating over a wide range of temperatures, up to 85°C. It also features over temperature protection, thermal shut down and efficient heat sinking to keep the device running in a safe thermal limit. It also has a remote On/OFF feature, allowing the device to be turned on or off without having to cycle the power, making it convenient to use in applications where remote control is required.

Overall, the TEA1753LT/N1,518 AC/DC converter module is a high efficiency, low cost solution for applications requiring an isolated AC input. Its features make it suitable for use in a wide range of applications, such as solar panel charge controllers, electric bicycles and appliances, LED lighting and battery chargers.
