Li Qi launched a full range of LED lighting power management solutions

The launch of LED lighting applications drive IC-RT84XX series rich technology is different from the day before, on the market a buck LED driver IC hysteresis control, rich full range of products with constant frequency and constant current control, the inductance value of hysteresis control to reduce the maintenance for 1/3, and fixed frequency mode and constant current control than hysteresis control do not change with the input voltage and current of LED due to the predetermined current accuracy variation.

Rich put different buck, boost and buck LED for LED lighting applications of different solutions. At present the product application on the market mostly adopt buck LED driver IC design, the number of LED drivers will be limited to the input voltage limited so as to require the use of a large number of IC buck boost or buck, if the driving mode can significantly reduce the LED buck drive usage and cost more than half of IC. The application circuit rich also address your needs and provide competitive design for customer reference. (as for lamp, lamp or lamp light steel frame system is to provide a 3.5~60V step-up or step-down power supply as the main application, such as the change of higher car brake lights or ship lights system to meet the 60V boost and buck for the main application)

According to the market in the MR16 and AR111 face because of electronic light source flicker problem is generated by the transformer, rich RT845X can be connected mode for customers of different LED chip on different drive circuit to provide the appropriate to solve the flicker problem facing customers. For the traditional voltage phase shift dimming demand, rich also issued a dimming circuit patent, allowing customers to compatible with existing systems and obtain a smooth adjustable luminosity. While other standard lamps such as GU10, E27, PAR30, PAR38 and other specifications to provide solutions.
