Additional Infomation About Product

SC440A High Effi ciency Integrated Driver for 6-Strings of 30mA LEDs POWER MANAGEMENT Features Description Wide input range 4.5V to 27V The SC440A is a high-effi ciency multiple string WLED 42V maximum output voltage with adjustable OVP for driver with an integrated boost converter. It operates smaller output capacitor over a wide input range from 4.5V to 27V with a maximum Drives up to 72 WLEDs in 6 strings output voltage of 42V and a 2A internal power switch. Programmable WLED current for up to 30mA per string It can drive up to 42V output voltage in 6 strings with 1% string-to-string current matching current up to 30mA per string. The string-to-string current 2A integrated power switch matching is 1% typical, 3% maximum and the overall Up to 91% effi ciency effi ciency is greater than 90% due to the low current sense 0.2% to 100% PWM dimming voltage and a low-impedance internal power switch. The Analog dimming wide PWM dimming range boasts a ratio of 500: 1. 800KHz switching frequency for small external com- ponent The 800kHz switching frequency enables the user to Open/short LED protection optimize the external component sizes for high effi ciency. Short LED protection disable When there are fewer LEDs in each string, users can use <1uA shut-down current a lower output voltage protection level which yields an Thermal protection allowable reduction in associated costs, size and voltage 4mm x 4mm x1mm MLPQ-24 package (Pb-free, Halo- ratings of the output capacitor. gen free, WEEE & RoHS compliant) The SC440A also features a comprehensive open and short circuit LED protection functions. It disables the Applications corresponding strings with LED open or LED short conditions while keeping other strings under normal Medium-sized LCD panel operation. This feature allows LCD panels to remain Notebook Display viewable even under LED failure, wire disconnect, or short- White LED Power Supplies circuit conditions. The short LED protection function can Sub-Notebook and Tablet Computer Displays be disabled. The internal thermal shutdown protects the Portable Media Players IC from overheating at abnormal conditions. The SC440A LCD Monitors is available in a common 4mm x 4mm x1mm MLPQ-24 Digital Video Cameras package.
