The TNY375DG-TL is a PMIC - AC DC Converters, Offline Switchers. It is well-applied in many applications such as lighting systems, consumer electronics, office automation and data storage products. A great feature of the TNY375DG-TL is it can operate from an AC line voltage with both single and multi-phase inputs of 120 V up to 276 V AC. It also includes a high performance universal input direct offline switcher.

The features of TNY375DG-TL enable system designers to provide optimal performance and reliability from a single device. It reduces the system design costs and support circuit designers with fewer boards, cost effective components and easier system manageability. The TNY375DG-TL also provides a suite of line protection features for circuit designs including line under-voltage lockout, brown-in voltage and over-voltage protection. The line under-voltage lockout automatically disables the power supply at the semiconductor level when the line voltage is detected to be below a user-defined level, while the brown-in voltage automatically resumes the power supply when the line voltage reaches a user-defined level.

The TNY375DG-TL is ideal for many applications as it is a highly integrated solution with a wide input voltage range that can operate in both continuous and pulsed conduction modes. It has a switch-mode power supply (SMPS) operating at 850 kHz that uses primary-side synchronous rectification, eliminating the need for secondary-side power switches. This minimizes components in the switching path, allowing greater efficiency and tighter output voltage regulation. The TNY375DG-TL also supports Active Clamp Reset Forward (ACRF) topology, allowing free-wheeling operations with Zero Voltage Switching (ZVS) and improved efficiency. In addition, the device is protected against short circuit and output over-voltage conditions and has an integrated voltage clamp on the device.

The TNY375DG-TL works to deliver a nominal 12W output power from a universal input voltage of 120 to 276 V AC. It utilizes a universal input design to reduce system design costs, supports a wide range of output voltages, and allows for system reconfiguration in the field. Additionally, its integrated power switches also help improve thermal performance and reduce energy losses, making it the ideal switching solution for a range of small- to medium-power systems. In addition, the device supports multiple protections, such as output over-voltage protection, and full range of normal and abnormal load protections, to ensure safe operation when the design and power system is under extreme conditions.

The TNY375DG-TL utilizes a proprietary Flyback topology to reduce one-time cost and system complexity. This patented technology is a high-performance solution that increases system value by reducing the number of components, and simultaneously improves power density and thermal performance while reducing switching losses. the device also provides a wide range of output voltage adjustments, allowing designers a great degree of flexibility in specifying the output power, while maximizing system efficiency. Furthermore, it offers short circuit protection, open loop protections and primary-side over current protections, allowing more reliable and safe operation even under extreme conditions.

The TNY375DG-TL offers exceptional performance at extremely low cost and is ideal for small- and medium-power applications. It has a wide operating range and offers excellent total energy efficiency, making it an ideal solution for systems with highly constrained form factors and limited budgets. Its high level of integration also helps simplifying circuit design and reduces system design costs. The TNY375DG-TL is also ideal for applications that require power changes on the fly, such as home lighting systems and consumer electronics, as its adjustable output voltage allows for changes to be made quickly and easily.
