Typical Performance Characteristics (Continued)

Efficiency Optimizer Auto Recalibration

The MSLB9082 is a stand-alone, eight-channel LED driver board suitable for integration into small-production devices. It

80mA in single-string mode, and 100, 120, 140, or 160mA in dual-string mode, and a switch to set the maximum LED

voltage to 39, 36, 32, or 28V. The board is powered from a single input voltage between 10V and 16V.

Input Power

The MSLB9082 board is powered from a single input voltage ranging from 10 to 16V.

Setting the Full-scale LED Current

The MSL3162 regulates the LED string current. The LED string current is set by a current sense resistor. Four different

values are programmed to the MSLB9082 LED driver module, and switch S2 selects one of those resistors to set the

full-scale, per-string LED current to 50, 60, 70, or 80mA. Table 4 shows the switch settings and the full-scale, per-string

LED current for each setting.
