TPS92401 LED Dot-Controllers

Texas Instruments TPS92401 LED Dot-Controllers are 4-channel, 5A LED devices with integrated PWM shunt FETs, an SPI interface, and an adaptive configuration. These LED drivers include a string of 4 series-connected integrated shunt FETs, each of which provides PWM dimming for an individual LED. The TPS92401 dot-controllers include an internal oscillator for a system clock to enable an integrated PWM generator up to 16-bit with programmable PWM frequency up to 60kHz. These LED dot controllers provide PWM dimming control of constant current regulators and enable multi-channel power saving to increase dimming efficiency in low brightness conditions. The TPS92401 devices are ideal for stage and photography lighting, surgical lighting, machine vision and IP camera LED array, cold/warm WLED lighting, 3D printing, and industrial transportation applications.
