Working Principle

The working principle of TEA1506AT/N1,518 is relatively simple and straightforward. It performs AC/DC switching and offline switching by using a power transistor which is driven by the PWM controller. Prior to the switching process, the voltage and current are first measured in order to determine the power transistor switching cycle and sequence.

The power transistor then turns off the current to the load, senses and latches the voltage, and turns on the current again, thus completing one cycle of AC/DC switching. During the switching process, the PWM controller is used to generate a PWM signal which is sent to the power transistor, controlling its switch between on/off states. The offline switching is also driven by the PWM controller.

When the power transistor is turned off, the PWM controller will detect and latch the voltage in order to detect the power off condition. Then it will bring the power transistor back to the on state and turn on the current again. This process will repeat cycle by cycle, thus completing the AC/DC and offline switching processes.

Conclusion

In conclusion, TEA1506AT/N1,518 is an AC/DC converter and offline switcher from Texas Instruments and it is widely used in energy-saving lighting, LED lighting, power transmission/receiving and household appliance applications. Its working principle is straightforward and it relies on the powerful PWM controller to drive the power transistor.
