AC DC converters are essential components used in modern electronic systems, such as computers, mobile phones, printers, and many other applications. The TIS 75-148 is a high frequency switching AC to DC converter that provides a low profile, robust, and efficient solution for powering various electronic systems, including computers, industrial instruments, automotive, and medical devices.

The TIS 75-148 converts an input AC voltage (110V-220V) to a regulated DC voltage output (3.3V to 42V). It operates by performing a series of switching operations on the input voltage to generate the required output voltage, thus providing a much higher efficiency than traditional linear converters. The TIS 75-148 uses MOSFETs for the switching operation, as well as low RDSon rectifiers for rectification of the AC signals. Its patented MX-Quad™ technology enables low power losses and fast transient response, making the TIS 75-148 a reliable and efficient choice for AC DC conversion.

The main application area of the TIS 75-148 is in medium-to-high power industrial and consumer electronics. Commonly used for computer, automotive, and medical applications, this converter can reliably provide DC output up to 200W. Additionally, its high frequency switching enables slimmer design size, thus making it suitable for applications that require minimal board space.

The working principle of the TIS 75-148 follows the established design of AC DC conversion, which involves a series of switching and rectification operations on the input AC signal to generate the desired DC voltage output. The core switching devices used in the TIS 75-148 are high efficiency MOSFETs that operate at a frequency of 50kHz to minimize power losses and reduce the board size. The device also includes low RDSon rectifiers that provide fast and reliable rectification of the AC signal.

The TIS 75-148 also has a slew rate control function that enables the device to reduce power dissipation during startup and shutdown cycles. This allows for smoother power supply startup and shutdown operations, thus improving the overall system performance. Additionally, the device also has an active current-sharing feature, which enables multiple TIS 75-148 converters to work in parallel and share load current equally.

In conclusion, the TIS 75-148 is a high frequency AC to DC converter that provides a reliable, efficient, and low profile solution for powering various electronic systems, including computers, industrial instruments, automotive, and medical devices. With its patented MX-Quad™ technology, the TIS 75-148 is able to provide low power losses and fast transient response, making it an ideal choice for applications that require minimal board space and high efficiency.
