TEA1723AT/N1,118

TEA1723AT/N1,118 is an offline AC/DC converter IC which provides high-quality power conversion between AC current and low voltage DC output. It is a compact, highly integrated IC with integrated fault protection, low standby power consumption, high efficiency and high power factor. This IC can be used to regulate output voltage and current accurately, provide over voltage and over current protection, and reduce ripple and noise. It is primarily used in mains-powered electronic devices such as white goods, lighting systems, SMPS power supplies and low power DC adapters.

The working principle of TEA1723AT/N1,118 is based on the principle of flyback transformers. The primary side of the transformer comprises a primary winding, a synchronous rectifier and a reset switch. On the secondary side, there is a secondary winding, rectifier diode and capacitor. AC current from a mains supply is applied to the primary winding, generating a magnetic flux which switches the synchronous rectifier and reset switch between high and low impedance states. In the low-impedance state, current flows freely through the primary winding, generating a stepped down high-frequency AC voltage which is applied to the secondary winding. This voltage is then rectified and filtered by the rectifier diode and capacitor, providing a low voltage DC output.

In addition to its core AC/DC converter, the TEA1723AT/N1,118 also provides a range of additional features to enhance its performance and safety. These include reset and standby functions, current limit and hiccup protection, and thermal and over-voltage protection. These features help protect against damage caused by hardware faults, power transients and other external hazards. The IC also provides integrated loop compensation, ensuring that the output voltage is accurately regulated at the desired level without oscillations or other irregularities.

The TEA1723AT/N1,118 is a very versatile IC and can be used in a wide variety of applications. It is suitable for use in a range of low power AC/DC converter designs, including white goods, lighting systems, SMPS power supplies and low power DC adapters. Due to its high efficiency and low standby power consumption, it is also suitable for Green Energy applications such as solar applications, wind energy conversion and electric vehicles.
