RT7304GE

The Richtek RT7304GE is a new type of LED driver IC that is designed for modern LED module applications. It is a PMIC (Power Management Integrated Circuit) specifically designed to provide efficient power conversion and regulation of LED modules. It features both Buck and Buck-Boost topologies, as well as a unique soft-start/soft-stop current control circuit, to allow for smooth and low-ripple LED module lighting.

The RT7304GE can be used in a wide range of LED module applications, such as LEDs for interior and exterior automotive lighting, LED home appliances and lightbulb replacements, outdoor landscape lighting, and general illumination for signs, displays, and architectural lighting. It is designed to give designers flexibility to experiment and optimize their LED designs to fit the specific lighting requirements.

The RT7304GE solutions are designed to be very efficient when operating in the transition of low to high current. This is possible by combining its Buck and Buck-Boost topologies as well as its customizable soft-start/soft-stop function to control the current consumption and ripple effects. The Buck topology allows for a low to very high peak current consumption transition with minimal power consumption in the low current range, and the Buck-Boost design allows for a similar transition for low to very high current consumption, with minimal stress on components when there is large fluctuations in current.

The RT7304GE also features a built-in soft-start/soft-stop control circuit that helps to reduce inrush current up to 70%, while reducing output ripple voltage up to 50%. The current consumption starts at a low value and gradually ramps up to the set current consumption value, which helps reduce system thermal stress, as well as noise and radio interference. The soft-stop circuit helps to reduce the current consumption to zero at a slow rate, which reduces system stress and helps protects components from damage.

Overall, the RT7304GE offers a powerful and flexible solution to meet the requirements of various LED module applications. It is designed to give designers flexibility while providing efficient power conversion and regulation of LED modules. Its Buck and Buck-Boost designs, as well as its soft-start/soft-stop control circuit, make the RT8304GE a great choice for high-efficiency and high-performance LED module applications.
