LYT4327E is a high-performance power and battery management integrated circuit (PMIC) AC-DC converter and an offline switcher. It is a multi-function integrated device that integrates high-frequency power conversion, battery charging, monitoring, and protection technology. LYT4327E meets the high-density, high-efficiency, high-current, and high-voltage requirements for power supply systems in many products. The device has an adjustable output voltage range of 5V to 24V. In addition, it also offers over-voltage protection, battery low voltage protection, and over-temperature protection functions.

The main application fields of LYT4327E mainly includes, but not limited: A. industrial control system; B. automotive energy system; C. home appliances; D. communications equipment; E. lighting control system; F. aerospace and military products. Different application fields require different input voltage, output voltage and rated current, which can be determined according to actual product requirements.

The working principle of LYT4327E is based on the power conversion from AC power to DC power. The AC voltage is applied to the input side, and is rectified and filtered to obtain a DC voltage. A high-frequency full-bridge inverter is used to convert the DC voltage into a high-frequency AC waveform. The high-frequency voltage waveform is applied to the output transformer, and the voltage and current are further adjusted to obtain the required output voltage and current. Finally, the output side is controlled to obtain the output voltage and current.

LYT4327E can provide up to 5A of continuous output current, up to 20A of peak output current, and up to 60mΩ of output side on-resistance. It has a wide temperature range of -40°C to +125°C, and is capable of working in harsh environmental conditions. In addition, LYT4327E also supports a wide input voltage range of 5V to 28V, high power conversion efficiency (up to 95%), fast response time (1~2μs), and no-load current of 5mA or less.

In summary, LYT4327E is an excellent AC/DC converter and offline switcher, as it can effectively and accurately convert power, follow strict safety standards, and provide high-power, high-efficiency, and high-accuracy performance. It is suitable for various power supply and battery management systems, and the main application fields include industrial control systems, automotive energy systems, home appliances, communication equipment, lighting control systems, and aerospace and military products.
