The TOP244G is a high performance yet cost-effective off-line switcher integrated circuit (IC) designed to provide an easy solution to a variety of AC/DC converting needs, while also providing transformer isolation. This cost-effective IC has been designed to lower the BOM (bill of materials) cost and eliminate multiple parts within a design.

The TOP244G is a constant frequency current-mode flyback power supply IC integrated with a 700V power MOSFET. It is designed to significantly reduce the total amount of components required to construct a working power supply system. The integrated features provide excellent line and load regulation, reduced output voltage ripple, high-efficiency performance and excellent power supply transient response characteristics.

The TOP244G is an integrated rectifying and switching solution for single-transistor forward converters as well as quasi-resonant or PWM mode flyback converters. It is also suitable for other applications such as LED drivers or lamp ballast controller. Its primary operating parameters are set with a few external components, allowing the designer to quickly set the desired application performance without having to operate with a large number of external components.

The TO-220F packaged TOP244G provides excellent reliability and performance and is intended for a wide range of cost-sensitive isolated applications. Its integrated features include an over-voltage/over-current/over-temperature protection system, as well as short-circuit protection, low-noise operation, fast startup time, and low stand-by power. The wide range of operating temperature and supply voltage ranges makes the TOP244G an ideal choice for various types of AC/DC applications.

The TOP244G is an SOI (silicon on insulator) based IC solution that incorporates a 700 V power MOSFET with integrated diodes on the same die. This makes the design simpler, more compact, and more cost-effective compared to traditional designs. The high voltage switch helps minimize thermal losses and results in a more efficient power supply. The integrated features make the TOP244G an attractive solution for a wide range of AC/DC applications with a very small BOM, low EMI, and low total system cost.

The TOP244G can operate in quasi-resonant or pulse-width modulation (PWM) mode, providing excellent line and load regulation, reduced output voltage ripple and high efficiency. It also offers high-performance protection features and fast start up time to ensure safety and reliability. The IC is designed to perform at a wide range of temperatures, providing excellent stability and immunity to a variety of environmental conditions.

The TOP244G is suitable for various types of AC/DC applications such as LED drivers, battery chargers, and lamp ballast controllers. It is designed with the integration of a MOSFET, a rectifier, and several other components into a single package, which significantly reduces the size and cost of the power supply system. Its performance, reliability and cost-effectiveness make it an ideal choice for multiple AC/DC applications.
