Working Principle

The TNY289KG-TL is a synchronous rectifier power component, which performs AC/DC offline switching. The principle of operation is simple and efficient. A rectifier converts the AC input power to a DC power and then passes the converted signal to the synchronous rectifier or the load. The load is then supplied with a DC signal.

The TNY289KG-TL uses a full-bridge topology, which allows the component to be operated with an open-circuit voltage range of up to 300Vrms. It also includes an alternate bridge-rectified secondary winding and a third winding for providing static line switching capabilities. A pulse-width modulation (PWM) control circuit is used to regulate the output current and prevent overshoot and noise. The component has built-in protection circuitry to protect against overvoltage, overtemperature, and overcurrent conditions.

The TNY289KG-TL also offers a wide range of switching frequencies, which gives the user maximum flexibility in setting the optimum efficiency for their application. The component also offers programmable overvoltage, undervoltage, short-circuit, and output current protection.

In addition, the TNY289KG-TL provides additional features such as a soft start, pre-current limiting and synchronization, which can be used to tailor the power performance to specific application needs. In all, the TNY289KG-TL is a highly versatile and efficient power management IC that can be used in a wide array of AC/DC power applications.
