LYT4228E3 is a highly efficient solution for AC/DC converter and offline switcher. It is a low-cost, high-efficiency integrated power solution for both AC and DC applications. The device integrates power converter and switching functions,such as power supply, line regulation, over-current protection, and output voltage tracking, into a single package. The device offers a complete solution for AC/DC power conversion, with safety and high efficiency, thus making it a preferred choice for designs that require cost-effective, power-efficient solutions.

LYT4228E3 features an advanced high-efficiency full bridge rectifier with synchronous MOSFETs and a 400V common mode choke deployment. This rectifier is designed to provide robust, reliable, and low-loss operation and is especially ideal for applications that require high-efficiency operation. The efficient rectifier enables current to flow without the need for snubbing and is compatible with a variety of AC power inputs, such as 230Vac, 420Vac, and more. The device also supports up to 400V HV supply and provides a comprehensive over-current protection during high AC input voltage.

The LYT4228E3 also features an efficient PFCB with a synchronous rectification circuit in order to improve efficiency and a frequency modulated (FM) switching operation for greater system flexibility and optimal operation. The PFCB synchronous rectification circuit allows for full power conversion from AC/DC to DC/DC and back, achieving efficiencies up to 95%. This rectification method also eliminates the need for snubbing, which simplifies the overall power conversion process and reduces cost.

The LYT4228E3 also has an advanced over-current protection feature which monitors the current draw and turns off the device if the current exceeds its limit. This prevents undue stress on the device and prevents damage due to excessive current draw. The device also incorporates a line regulation feature to maintain the output voltage even when the AC input voltage fluctuates. This ensures that the power supply remains stable and consistent even when the AC voltage fluctuates.

In addition to its AC/DC conversion capabilities, the LYT4228E3 also offers an offline switching solution. This allows for power conversion from DC/DC to AC/DC, or vice versa. The device features a temperature-controlled startup circuit, which helps to ensure that the device starts up safely even in extreme temperature conditions. The device also offers an additional level of protection by shutting down the power when the temperature exceeds its specified limit. It is important to note that the device is designed to operate in an environment where the ambient temperature is higher than the device’s specified temperature range.

The LYT4228E3 is an ideal solution for designs that require a robust and efficient power solution. It provides high efficiency power conversion with over-current protection, line regulation and temperature control. The efficient full bridge rectifier, PFCB synchronous rectification circuit, FM switching, and temperature controlled startup circuit offer an optimal performance even in extreme temperature conditions. As a result, the LYT4228E3 is an ideal solution for applications that require cost-effective, power-efficient solutions.
