L6598BDTR is an advanced version of the popular L6598 single-chip isolated AC DC converter and is the best solution for advanced offline switch applications. This offline switcher offers a wide input voltage range, high power density, and a wide range of output voltages, making it ideal for a wide range of applications ranging from lighting and home appliances to relays and UPS system.

The L6598BDTR is based on a synchronous rectification topology, which eliminates the need for external rectifiers, leading to a highly integrated design with reduced electricity loss. Its integrated digital controller and advanced protection features, such as over-current, over-temperature, and short-circuit protection, ensure reliable operation and protect the system from unexpected faults.

The working principle of the L6598BDTR is quite simple. First, the AC input is rectified, filtered, and converted to DC by the diode bridge rectifier. The DC output is then stepped down to the desired voltage by the output transformer. The secondary winding of this transformer is connected to a MOSFET switch, which is then modulated by the integrated digital controller to generate a constant output voltage.

The L6598BDTR is a highly reliable and efficient offline switcher that provides a wide range of output voltages from 3.3V to 37V. It has a wide operating temperature range (-40°C to +85°C), a wide input voltage range from 85 to 265VAC, and a high efficiency rating of up to 94.5%. The device also includes a programmed soft-start and standby mode for reduced power consumption and accurate current limiting for improved system protection. The integrated group voltage regulation feature allows better tracking of multiple outputs, resulting in improved system performance.

The L6598BDTR is an excellent choice for a wide range of applications, including LED lighting systems, consumer appliances, security systems, and other electronic components. It is designed to meet the needs of the market and provides users with a reliable and cost-effective solution. The device comes with built-in protection features, such as over-voltage, over-temperature, and short-circuit protection, to ensure reliable operation and long-term system integrity.
