The TPS92402 LED dot-controller device enables 8-channel individual lighting solutions by providing up to 2.5A pixel-level LED dimming control with 4.5V to 65V wide input range. The device includes a string of 8 series-connected integrated shunt FETs, each of which providing PWM dimming for an individual LED. The shunt FET string allows the device to support constant current regulators with either commmon-anode or common-cathode LEDs. The TPS92402 has an internal oscillator for a system clock to enable integrated PWM generator up to 16-bit with programmable PWM frequency up to 60kHz. The serial peripheral interface (SPI) enables high speed data transmission and supports both daisy chain and star connections. The SPI and optimized pinout allow multiple devices connected in stacking configuration for single-layer PCBs. The TPS92402 incorporates registers for programming PWM pulse width, slew rate, edge shift and open voltage of each individual LED in the string and for reporting LED open, LED short, shunt FET open and thermal warning. The internal charge pump incorporates spread spectrum feature to enhance EMI performance. The TPS92402 also provides PWM dimming control of constant current regulators and enables multi-channel power save to significantly increase dimming efficiency especially in low brightness condition.
