TOP256LG is a power management integrated circuit (PMIC) developed by Power Integrations. This device integrates AC/DC and offline switcher functions into a single IC, making it a great choice for applications that require efficient power management. The TOP256LG can be used in a variety of applications, including LED lighting, security systems, and smart appliances.

The AC/DC converter function of the TOP256LG is used to convert an AC input voltage to a DC output voltage. It has an internal PWM control loop that enables it to operate in either continuous conduction mode (CCM) or critical conduction mode (CRM). This allows for higher efficiency, improved power factor, and reduced EMI in the end system. The TOP256LG also features a low operating frequency and a wide input voltage range from 80 VAC to 305 VAC, making it ideal for many applications.

The offline switcher function of the TOP256LG provides a complete power conversion solution with integrated rectification, power factor correction (PFC), and low standby power. This feature helps reduce the size and cost of the end system. In addition, the TOP256LG’s integrated thermal and overvoltage protection ensures that the device is safe to use in the most demanding applications. It can be used in a variety of topologies, including flyback and forward converter designs.

The TOP256LG is a versatile, cost-effective solution for designing efficient, safe, and reliable power management applications. Its integrated AC/DC converter and offline switcher functions make it well-suited for a wide range of applications, including LED lighting, security systems, and smart appliances. Its features, such as low operating frequency and wide input voltage range, make it a great choice for applications requiring reliable, efficient power management.
