PMIC - AC DC Converters and Offline Switchers are becoming increasingly popular, and their applications are many. The TNY290KG-TL is one such device, a single-output AC/DC switcher with a 1A maximum output current and an operating temperature range of up to 105°C.

The device includes a 5V/2A input voltage regulator, a 30KHz fixed frequency oscillator, and a Pulse Width Modulation (PWM) controller for precise control of the output voltage and current. The TNY290KG-TL has a fast 0.7V start-up voltage from cold, and a soft-start to reduce in-rush current and over-current protection.

The TNY290KG-TL has many features, such as an enable/disable pin, an under-voltage lockout protection, thermal shutdown protection, and current limit protection. The device also features an integrated transformer, allowing for a bidirectional logic signal signal that can be used to control the output voltage, as well as its slope compensation to optimize the output performance.

The device is primarily used in applications like power supplies for digital devices, server and computer systems, and communications systems. It is also used in the automotive industry, in engine control systems and the charging of electronic components such as sensors and regulators. Other applications include battery chargers, and audio amplifiers.

The TNY290KG-TL can also be used in conjunction with other devices such as Schottky diodes, MOSFETS, and controllers, to create customized DC power converters and mains powered AC/DC converters. With its wide range of features, the TNY290KG-TL is an excellent choice for many applications involving voltage and current regulation.

In terms of its working principle, the TNY290KG-TL is designed to take an alternating current (AC) input and convert it into a direct current (DC) output. The device works by stepping down the given AC input voltage to a predetermined level that can be supplied to the output. The device then uses a Pulse Width Modulation (PWM) controller to control the output voltage and current, providing precise control of the output and allowing for power saving.

The device also includes several safety features such as under-voltage and over-current protection, enabling the device to shut down in the event of a failure and protecting the device from any potential damage. Additionally, the TNY290KG-TL includes a thermal shutdown protection feature that helps protect the device from any potential temperature related problems.

The TNY290KG-TL is a very versatile device, capable of being used for many different types of applications requiring voltage and current regulation. Its variable input voltage capabilities, numerous protection features, and precise control make it an ideal choice for a range of AC/DC converter applications. Its compact size and easy installation make it an attractive option for anyone looking for a convenient, reliable and efficient AC/DC converter.
