SC5012QMLTRT

SC5012QMLTRT is a high efficiency 4-Ch, 150mA/Ch LED driver with I²C interface and phase-shifted PWM dimming designed for backlight applications. It features wide input voltage range (4.75V to 45V), flexible output configuration, wide analog and PWM dimming range, phase shifting, optional fading, external boost controller frequency synchronization (FSYNC), I²C interface, and numerous protection features. The boost controller, with programmable switching frequency from 200KHz to 2.2MHz, can maximize efficiency by dynamically minimizing the output voltage while maintaining LED string current accuracy. It provides excellent line and load response with no external compensation components. Each linear current sink is matched within ±1% for superb lighting uniformity, and the accuracy of each string current is ±2%. Application includes medium-sized LCD pane, automotive car navigation/information display, LCD monitors, automotive AEC-Q100 qualified application.
