This converter-based series of DC/DC solutions helps manufactures to reduce system cost and the total energy consumption

The TNY289PG series of AC/DC converters offer high performance, robust hardware and comprehensive software solutions for the modern power management and control. It offers an efficient and cost-effective solution for powering any number of consumer electronics, home appliances and other consumer applications. The series is designed with a focus on high efficiency, low standby power and high speed switching.

The features of TNY289PG series of AC/DC converters include an input voltage range of 110V - 240V and a wide AC-DC conversion range of 0-10V. This series also offers high efficiency switching with low harmonic noise, high efficiency and high power factor. The converters also feature internal EMC filter, adjustable output, integrated junction temperature monitor, I2C monitor for system health, and more.

The structure of TNY289PG series of AC/DC converters consists of an input rectifier, main transformer, Magnetics and integrated MOSFETs. In addition, it includes a PFC controller, a controller IC, an isolation transformer and an EMI filter. The rectifier converts the AC current into DC current, while the transformer and other components help to regulate and control the current flow.

The working principle of TNY289PG series of AC/DC converters can be divided into four main stages: AC rectification, input current regulation and PFC control, DC/DC conversion, and post regulation and output protection. The AC rectification stage rectifies the current from the AC power source and is followed by the input current regulation, which is used to reduce the ripple and regulate the current. The PFC control stage helps reduce the power harmonic distortion. The main DC/DC conversion stage utilizes the main switching components along with the controller IC to convert the input voltage into a fixed output voltage, which is then regulated by the post-regulation and output protection stages to ensure the output voltage and current are maintained within the specified range.

Overall, the TNY289PG series of AC/DC converters offer reliable, advanced power conversion solutions for the modern digital devices and home appliances. Their comprehensive features and components, combined with robust design and high efficiency switching make them a great choice for applications where high power and reliability are a necessity.
