AC-DC Isolated LED Drivers
AC/DC isolated LED drivers can support designs for safety requirements in particular for high power applications. Richtek’s LED driver solutions help engineers simplify designs by using primary and secondary side controls while maintaining tight current regulation. Our products feature high power factor, fast start up, analog and PWM dimming functions.
AC-DC Non-Isolated LED Drivers
AC/DC non-isolated LED drivers can achieve high efficiency with less BOM count, ideal for cost-sensitive LED lamp replacement. Richtek’s LED driver 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.
DC-DC LED Drivers
Richtek has developed the variety of DC/DC converters and controllers LED drivers for battery-powered system or two stage topology with ultra-low power consumption and 1% precise dimming performance.
