The LNK4023S-TL is a state-of-the-art AC/DC off-line switching converter that is used to reduce power. It is a part of the Power Management ICs (PMICs) family and is used to provide AC current and voltage conversion for applications such as personal computers, home appliances, OA equipment, for intelligent control and other analog or digital circuits.

The LNK4023S-TL is a fully integrated, single stage, offline switching regulator with a built-in MOSFET power switch, flexible protection features and a high efficient (> 90%) Zero Voltage Switching (ZVS) topology. It features high efficiency and ultra low EMI, and is suitable for operating up to 400VAC (60Hz) with a 4-pin package configuration, making it ideal for design into space-constrained AC/DC power supplies. Its integrated flyback topology varies the primary side voltage to provide an adjustable output voltage. The built-in 55V/650mA internal MOSFET enables AC-DC converters to achieve high efficiency and low EMI performance.

The working principle of the LNK4023S-TL is based on the ZVS full-bridge topology. A symmetric bridge with two transistors and two diodes is used, instead of a diode-capacitor full-bridge structure. This structure, when combined with a PWM control, allows the output voltage to be adjusted and the power switch current to be compared in order to reduce the total harmonic distortion. The operation of the device is based on the switching frequency, the duty cycle of the output voltage and the voltage and voltage drop. The LNK4023S-TL also offers a wide range of protection features, such as an overvoltage protector, an overcurrent protector and a thermal shutdown device.

The LNK4023S-TL can be widely used in consumer electronics, industrial control, communication and medical applications. It is widely used for power supplies, adapters, industry-controlled sound systems, security lighting, medical instruments, etc. It can also be used to regulate and stabilize AC and DC voltages for a wide range of applications such as the burglar alarm systems, monitoring systems, metering systems and rooftop inverters. It is also suitable for many solar energy system applications.

The LNK4023S-TL is a powerful AC/DC switch mode power supply that offers high efficiency, ultra low EMI performance, wide operating frequency range and advanced protection features. It can be used in a wide array of applications, as it can power both DC and AC applications. The device also provides an easy solution to reduce power consumption in sensitive applications, and its features make it a powerful choice for designers who need to design an efficient, stable, low EMI AC/DC switch mode power supply.
