Additional Infomation About Product

RT7321 Linear LED Driver for High-Voltage LED Lamps General Description Features AC Input Voltage Range : 200 to 240V RMS The RT7321 is a simple and robust constant-current No Electrolytic Capacitor and Transformer regulator designed to provide a cost-effective solution for Required driving high-voltage LEDs in LED lamp applications. The Improved LED Utilization RT7321 is equipped with a proprietary control mechanism Programmable LED Current to improve the utilization of high-voltage LEDs. The RT7321 Thermal Regulation Protection allows users to set the regulated current levels (WQFN- High Power Efficiency 20L 5x5 Package) for various LED lamps. It also provides High Power Factor low pin-count SOP-8 (Exposed Pad) package with Easy EMI Solution customized current setting to meet various application Minimized BOM Cost and Space Required requirements. In addition, the RT7321 also provides a RoHS Compliant and Halogen Free thermal regulation protection, instead of traditional thermal shutdown, to suppress the rise of the temperatures in LED lamps and prevent the LED lamps from flicker.
