The TPS61193-Q1 is an automotive high-efficiency, low-EMI, easy-to-use LED driver with integrated DC-DC converter. DC-DC converter supports both boost and SEPIC mode operation. Device has three high-precision current sinks that can provide high dimming ratio brightness control with a PWM input signal.

The DC-DC converter has adaptive output voltage control based on the LED current sink headroom voltages. This feature minimizes the power consumption by adjusting the voltage to the lowest sufficient level in all conditions. DC-DC supports spread spectrum for switching frequency and an external synchronization with dedicated pin. The high switching frequency allows the TPS61193-Q1 to avoid disturbance for AM radio band.

The input voltage range for the TPS61193-Q1 is from 4.5 V to 40 V to support automotive stop/start and load dump condition. The device supports PWM brightness dimming ratio 10 000:1 for 200-Hz input PWM frequency. The TPS61193-Q1 integrates extensive fault detection features.
