LYT4326E is an AC/DC converter developed by LiteOn Technology Corporation. It is part of the company’s power management integrated circuit, or PMIC, portfolio and is considered an offline switcher. The device’s primary purpose is to convert standard alternating current (AC) electrical power into a direct current (DC) format and provide power to a connected device. The LYT4326E is an energy efficient and cost-effective solution for modern power management needs in a wide range of applications.

The LYT4326E is able to take on inputs of 100 to 277 volts AC, a very wide range and appropriate for use in virtually any commercial or residential environment. This high input range meets U.S. National Electrical Code requirements for Class 2 applications and provides additional flexibility for custom applications and designs. The device can also support both constant voltage (CV) and constant current (CC) LED drivers with an output current of up to 1000mA. It also has an excellent efficiency of up to 95%, so that the power dissipated is kept to a minimum.

In addition to its impressive efficiency, the LYT4326E is also housed in a compact, flat SOT-23-5 package. This package is smaller than traditional converter designs, allowing it to fit into even the most compact designs and free up additional space for other components. The device is also highly reliable, with an MTTF of 120K hours and a line regulation of ±1%. The included over voltage protection (OVP), over current protection (OCP), and short circuit protection (SCP) also make it a robust device suitable for a variety of power applications.

The LYT4326E is ideal for a variety of applications, particularly those that require an intermittent signal or require rectification for a specific output voltage. These include LED lighting and driver applications such as low-power LED applications, light bars, remote controls, white goods, air conditioners and other small household appliances. It is also well suited for automation systems, medical equipment, and professional audio and video equipment.

The working principle of the LYT4326E is based on a buck-boost or buck-flyback topology. This topology allows the circuit to convert AC input power into a DC output voltage. The device can function either in a continuous-on or single pulse-on mode for both input voltage and output current regulation. In addition, the integrated high voltage MOSFETs provide low-loss power conversion and the included internal compensation circuits ensure maximum stability.

Overall, the LYT4326E is an excellent choice for power conversion in a variety of applications due to its high reliability, excellent performance, and low-cost. Its wide input range and high efficiency also make it a cost-effective solution for both commercial and residential applications. Its versatility, small package size, and robust protection features make it an attractive choice in almost any power application.
