LYT5226D

LYT5226D is an AC DC converter, offline switcher, and PMIC (Power Management Integrated Circuit) device. It is designed to provide an efficient, low-cost power solution. The device is ideal for applications such as motor control, lighting, ultrasonic motors, and power supplies. It features a 3.3V input voltage range, an 8A peak current output, and a component count of two-electronics for low component cost and assembly.

The device utilizes a half-bridge topology with input bridges that can be connected directly to the line-voltage, or via a bridge rectifier. In the bridge rectifier configuration, the LYT5226D operates as a half-bridge using two phases, with either positive or negative polarities. The input bridge is also connected directly to the output stage, providing a low-cost, low-noise design. The device is capable of generating output voltage signals from 0 to 12V, with a selectable frequency range of 5kHz to 50kHz.

The LYT5226D features an integrated control circuit, allowing the input frequency to be varied in order to optimize the power output depending on the application. In addition, the device incorporates a simple built-in auto-restart function, allowing it to restart after a power cycle. This auto-restart function eliminates the need for manual resetting and increases the reliability of the device.

In addition to its low-power and efficient performance, the LYT5226D also offers robust protection features. It includes an overvoltage and undervoltage protection, as well as built-in linear current limit and temperature protection. Furthermore, the device also includes an adaptive over-temperature shutdown for additional safety. These features make the device suitable for use in applications where safety is a primary concern.

Overall, the LYT5226D is an ideal solution for a wide range of AC DC converters, offline switchers, and PMIC applications. With its integrated control circuit, overvoltage and undervoltage protection, and built-in auto-restart function, the device provides an efficient and reliable power management solution. Additionally, its robust protection features and adaptive over-temperature shutdown make the device a suitable choice for safety-critical applications.
