Diodes' AL5822 is an adaptive linear-current controller targeted to suppress low-frequency LED current ripple. When combined with single-stage, constant-current, high-power-factor LED drivers (AL1665), the device can provide a high-power-factor and low-ripple solution that meets commercial lighting’s high performance requirements. The AL5822 has a high-efficiency driving mechanism that suppresses the LED current ripple without any sign of flickering and strobing. The AL5822 has many built in protection features, such as overtemperature protection (OTP), overcurrent protection (OCP), and LED short-circuit protection (SCP). The AL5822 is available in the SOT26 package.
