- STEVAL-TLL012V1, Demonstration Board using STP4CMP charge pump based 4-channel LED driver designed for RGB illumination or LCD display backlighting. This device works off a battery with an input voltage between 2.7 V - 5.5 V. The device generates regulated current sinks with high absolute and channel-to-channel accuracy to drive up to 4 LEDs. It can support LEDs with forward voltage as high as 3.8 V. The PWM control can be applied directly to the 4 EN (enable) inputs to provide brightness control
