The TPS92401RRVEVM helps designers to evaluate the characteristics, operation and use of the TPS92401 device. The TPS92401 LED dot-controller includes a string of 4 series-connected integrated shunt FETs, each of which provides PWM dimming for an individual LED. In conjunction with front-end buck constant current regulators (CCR), The TPS92401 enables 4-channel individual lighting solutions by providing up to 5A pixel-level LED dimming control with 4.5V to 65V wide input range.
