The LNK500G is an integrated offline switcher from Power Integrations. It is designed to provide a cost-effective Integrated Power Solution for AC to DC applications. It is primarily used in consumer electronics and power supplies.The LNK500G works by first taking incoming AC power and using a bridge rectifier to convert it to DC power. This DC power is then turned into a high frequency alternating current. This alternating current is then used to power an inductor, a diode and a transistor which in turn generate a low voltage DC supply. This DC supply is used to drive a switching MOSFET to generate an isolated DC output.The LNK500G includes various safety features such as an over-voltage protection circuit and a current limiter. It also includes advanced control functions such as peak current mode control and burst mode operation. This allows the output voltage to be adjusted over a wide range with a minimum of external components.The LNK500G is highly efficient, with power losses at full load typically below 1W. It is designed to meet the tight efficiency and standby power requirements of consumer electronics and other low power applications.The LNK500G is available in multiple package types and can be used in a variety of different applications. Typical applications include:• Power adapters• Point-of-load dc-dc converters• Battery chargers• LED lighting• Industrial control systemsThe LNK500G also supports multiple input configurations, such as single ended, double ended and isolated. This makes it an ideal solution for a wide range of power supply design requirements.Overall, the LNK500G is an excellent solution for low power AC to DC applications, offering both high efficiency and low cost. It is a reliable solution that offers a wide range of features and configurations.
