It can be operated from either universal AC line or any DC voltage between 8-450V. Optionally, a passive power factor correction circuit can be used in order to pass the AC harmonic limits set by EN6100-3-2 Class C for lighting equipment having input power less than 25W. The IL9910 can drive up to hundreds of High-Brightness (HB) LEDs or multiple strings of HB LEDs. The LED arrays can be configured as a series or series/parallel connection. The IL9910 regulates constant current that ensures controlled brightness and spectrum of the LEDs, and extends their lifetime. The IL9910 features an enable pin (PWM_D) that allows PWM control of brightness. The IL9910 can also control brightness of LEDs by programming continuous output current of the LED driver (so-called linear dimming) when a control voltage is applied to the LD pin. The.
