PMIC (Power Management Integrated Circuit) AC DC converters and offline switchers are essential components for any system which relies on regulated power sources. The TOP247R-TL, a high voltage offline switcher manufactured by Power Integrations, Inc., has become a popular choice for a wide range of applications.

The TOP247R-TL is an integrated flyback AC/DC converter operated over a wide input range from 90 VAC to 265 VAC and output adjustable from 4.5 V to 24 V. It features a high efficiency of up to 90%, low standby power consumption of 1.2 Watt and a ripple and noise of 75 mV peak-to-peak.

The TOP247R-TL is designed for a wide range of applications, such as motor controllers, adapters, UPSs, or various types of power supplies. It features a protective circuitry, which switches off the power when an over voltage condition has been detected. This helps ensure a reliable and secure operation of the system.

The TOP247R-TL also includes a variety of other features to increase system performance and protect the converter from over-current, over-temperature, and overtemperature conditions. It has the capability to monitor the line voltage, allowing system designers to quickly adjust the output voltage according to application requirements.

In terms of its working principle, the TOP247R-TL relies on a series of feedback loops to regulate and control the output voltage. High voltage AC is rectified and filtered, then conditioned via an active rectification circuit, a linear regulator, and a frequency converter to a regulated DC. The output voltage is then regulated to the preset level.

The TOP247R-TL continuously monitors the output voltage and current conditions, and will adjust the output voltage accordingly in order to ensure stability. As mentioned above, the TOP247R-TL features a number of safety features which will protect the converter from over-voltage, over-temperature, and overtemperature.

Overall, the TOP247R-TL is a highly efficient, reliable, and affordable AC/DC converter designed for a variety of applications. Its wide range of features, coupled with the protection circuitry and automatic feedback monitoring make it a great choice for any application requiring regulated power.
