The TNY266GN-TL is one of the many AC/DC converters and offline switchers available in the PMIC (Power Management Integrated Circuit) market. It is an integrated circuit that provides a low output ripple, high efficiency and low power dissipation in a compact package. Its intended applications include personal computers, telecom equipment, industrial control, switching regulators, SMPS (switched mode power supply), and battery charger systems.

The AC/DC converters use a modified buck switching regulator or buck-boost regulator to convert AC input power to a DC output voltage. The output voltage is controlled by adjusting the switching frequency of the regulator. This type of converter offers high efficiency, low output ripple and considerably less power dissipation compared to linear regulaotrs. The TNY266GN-TL has integrated over voltage protection, so that in the event of a transient overvoltage, the regulator will shut down to prevent power supply damage.

Offline switchers are switch mode power supplies that use a primary side controller and an isolated power stage to convert an AC input voltage to a DC output voltage. The initial power stage is usually a switch operating at a fixed frequency. The power stage typically delivers power to the output through an inductor, holding a controllable switch, either on or off. The TNY266GN-TL includes additional features such as a precision current limit and a short-circuit protection that allows it to operate in a wide variety of applications.

The working principle of the TNY266GN-TL is straightforward. It monitors the input voltage and adjusts the switching frequency and duty cycle to maintain the output voltage at the required value. The output voltage is regulated by comparing it to an internal reference voltage and making the necessary adjustments. It also includes features such as over temperature protection and under voltage lockout, as well as adjustable soft start, current limit and frequency control. Furthermore, the device is designed for operation over a wide temperature range.

The TNY266GN-TL is an excellent choice for a wide range of applications, from personal computers and telecom equipment to industrial and battery charger systems. This highly integrated solution offers low output ripple and high efficiency, while providing protection to the power supply in the event of over-voltage or short-circuit conditions.
