The MSL3167 compact, high-power, 16 parallel string LED driver feature internal current control MOSFETs that can sink up to 30mA per LED string with better than 3% accuracy. These devices drive up to 10 white LEDs per string, for up to 160 LEDs per MSL3167. A single PWM input controls the PWM period and duty cycle for all strings. The MSL3167 include automatic fault management of string open circuit, short circuit and over-temperature conditions. Faults are alerted on the FLTB pin, and fault status is optionally available through the I2C/SMBus-compatible serial interface. The MSL3167 adaptively control the DC-DC converter that powers the LED strings using mSilica's Adaptive SourcePower™ technology. This Efficiency Optimizer minimizes power use while maintaining LED current accuracy. A single, external resistor provides the global reference current for all the LED strings. The MSL3167 operates all 16 strings in phase.
