FEATURES
●● High Efficiency 8-Channel LED Driver with I2C Interface and Phase-Shifted PWM Dimming
DESCRIPTION
An optional disconnect p-MOSFET provides true load disconnection and inrush current limiting. The boost controller, with programmable switching frequency from 200kHz to 2.2MHz, maximizes 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%. An external resistor adjusts the current from 10-50mA per string. It also features PWM dimming resolution of 9 or 10 bits (user selectable) over dimming frequency from 100Hz to 20kHz, synchronized to the SYNC signal or the boost oscillator. String-by-string phase shifting reduces the demand on the input/output capacitance, decreases EMI, and improves dimming linearity. SC5010H is available in a low-profile, thermally enhanced, 4 X 4 X 0.6(mm) QFN 28-pin package.
