SM4002PL-TP Discrete Semiconductor Products

SM4002PL-TP is a high-efficiency, dual-channel synchronous high-frequency rectifier provided by Alpha & Omega Semiconductors, Inc. It is suitable for use in various applications such as lighting and power supply systems, power adapters, notebook computers, and electronic appliances.

The device is designed to provide high efficiency, low leakage current and high reliability. The SM4002PL-TP is a dual-channel synchronous rectifier that can be used in a variety of switch power supplies and other applications. It has an integrated thermal shut-off and over-voltage protection. The device is available in a tiny, 4.3 mm × 2.3 mm QFN8 package with 0.5 mm pitch, allowing for a wide range of design options.

The main application field of the SM4002PL-TP is power adapters. It helps to reduce the power adapter size and reduce power losses. It is also used in other types of applications such as laptops, tablets, white goods, Bluetooth speakers and vehicle chargers.

The working principle of the SM4002PL-TP is based on synchronous rectification. It uses an active device as a switch to replace the traditional diode in the power supply circuit. This reduces the power losses in the circuit and increases efficiency. The device works by sensing the DC link voltage and opening the switch when the voltage reaches a certain level. This ensures that the power switch is turned off and no longer conducts, thereby improving efficiency.

The SM4002PL-TP device provides over-voltage protection, as well as integrated thermal protection. The over-voltage protection prevents the circuit from damage due to excessive voltage, while the thermal protection shuts off the device if the internal temperature rises above a predetermined threshold. These two features help to improve circuit reliability and protect the device from damage due to over-voltage or overheating.

The SM4002PL-TP is a high-efficiency, dual-channel synchronous high-frequency rectifier that is suitable for a variety of applications. It offers high efficiency, low leakage current, over-voltage protection and integrated thermal protection. It is used in power adapters, laptops, tablets, white goods and other applications.
