The IL9910DT-B is an LED driver integrated circuit manufactured by IK Semicon. It is a low voltage, 8-bit SOIC-8 (Small Outline Integrated Circuit) in a RoHS (Restriction of Hazardous Substances) compliant package. It is capable of driving up to 8 LEDs. The device can operate in three different modes: direct PWM dimming, 4-bit channel current dimming, and extended duration dimming. The device also has an integrated overvoltage protection (OVP) and open drain brown-out protection (BOP) for LED center string operation. The device consumes very low power, and its operating temperature range is from -40C to +85C for operation.
