Texas Instruments TPS92691/TPS92691-Q1 Multi-Topology LED Driver is a versatile LED controller that can support a range of step-up or step-down driver topologies. The device implements a fixed-frequency peak current mode control technique with programmable switching frequency, slope compensation, and soft-start timing. It incorporates a high voltage (65V) rail-to-rail current sense amplifier that can directly measure LED current using either a high-side or a low-side series sense resistor. The amplifier is designed to achieve low input offset voltage and attain better than ±3% LED current accuracy. This is done over a junction temperature range of +25°C to +140°C and output common-mode voltage range of 0 to 60V. The TPS92691-Q1 devices are AEC-Q100 qualified for automotive applications.
