The LED drivers for lighting applications need to ensure stable constant current for brightness consistence control, and also need high efficiency and high Power factor for energy saving. We offer numbers of application note for all kinds of LED light fixture ranging from AC input such as A-lamp/PAR/T8, 12Vac input MR16 to smart lighting application to help you select the right product. We also provide flicker-free solution for light quality improvement.
AC/CC non-isolation LED drivers can achieve high efficiency with less BOM count that are well suited for cost sensitive LED lamp replacement. Richtek’s solutions feature high-efficiency, high power factor, excellent current regulation and few EMI components. Furthermore, our THD compensation design enables system to pass IEC-61000-3-2 class C in buck configuration.
AC/CC isolation LED drivers can support the design for safety requirements especially in high power application. Richtek’s solutions can help designer simplify the design by using primary side control while current regulation is still tight. Our products features high power factor, HV start up, analog and PWM dimming functions.
AC/CC Triac dimming
AC/CC Triac dimmable LED driver ensure system to work smoothly with Triac dimmer. Richtek’s solutions provide good compatibility with many kinds of triac dimmers while keeping system in high efficiency and low BOM cost.
DC/CC Buck, Boost and Buck-Boost
DC/CC can be used in battery system or two stage topology. Richtek’s comprehensive DC/CC solutions can serve all your needs.
Two stage MR16
MR16/AR111 light fixture need to match with 12Vac from different kinds of electronic transformer. Richtek unique two stage LED driver provides very high ET compatibility, high power factor in compact SOP-8 package. Our design can ensure your product high performance and high reliability.
Smart lighting solutions
Smart lighting design need to work with different kinds of wires control module, and for energy saving standby power consumption must be low. Richtek’s solutions can provide you the simplest design with the lowest power consumption in standby mode.
