The TNY290PG is a universal adapter AC/DC converter and offline switcher product designed with a working principle that can, in relatively low volumes, power various applications with nominal power up to 15W. The product, which comes with a number of different cooling and PCB layouts, can be used in applications that require constant DC power supply, including portable radios, set top boxes, and game consoles.

This TNY290PG product is part of the PMIC – AC DC Converters, Offline Switchers category. It was specifically designed to support North American and European markets with an output voltage of 3.3V, 5V, 12V, and 15V. The integrated primary circuit also allows for a wide range of secondary topologies. In order to reduce component counts and component size, the product also contains a high voltage PWM controller.

The TNY290PG works through the use of front-end PFC and CCFL boost controllers. This static power conversion technique requires no inrush current limiting, allowing partial power MOSFETs to directly drive the secondary AC/DC converter at full load. The magnetic components are also designed to operate at temperatures ranging from -45°C to +105°C. This makes it suitable to be used in most applications.

The offline switcher portion of the product helps to ensure that the output of the converter is maintained within the specified range. This is done through the use of high frequency PWM controllers, MOSFETs, and inductors. The controller sets the switching frequency of the converter, while the MOSFETs and inductors regulate the power output of the converter.

In addition to its offline switcher, the TNY290PG also contains an input voltage recognition circuit. This circuit is designed to detect the input voltage and provide an indication that the input voltage is outside of its predetermined range. The indication could then be used to trigger a slew rate limiting circuit or a hardware reset of the system.

The TNY290PG also contains other features such as power limiting and thermal protection circuits. The power limiting circuit is designed to prevent overload and ensure constant power operation. The thermal protection circuit is designed to ensure that the product remains within its safe operation range by limiting its maximum power dissipation.

In summary, the TNY290PG is a feature-rich, universal adapter AC/DC converter and offline switcher product that can power various applications with nominal power up to 15W. It is specifically designed to support North American and European markets with an output voltage of 3.3V, 5V, 12V, and 15V. The integrated primary circuit also allows for a wide range of secondary topologies. The product includes features such as power limiting and thermal protection, making it a suitable choice for powering various applications.
