Texas Instruments  TPS61193PWPRQ1

The TPS61193-Q1 is an automotive high-efficiency, low-EMI,easy-to-use LED driver with an integrated DC-DC converter. The DC-DC converter supports both boostand SEPIC mode operation. The device has three high-precision current sinks that can be combinedfor higher current capability.

The DC-DC converter has adaptive output voltage control based onthe LED current sink headroom voltages. This feature minimizes the power consumption by adjustingthe voltage to the lowest sufficient level in all conditions. For EMI reduction DC-DC supportsspread spectrum for switching frequency and an external synchronization with dedicated pin. Awide-rage adjustable frequency allows the TPS61193-Q1 to avoid disturbance for AM radiobands.

The input voltage range for the TPS61193-Q1 is from 4.5 V to 40V to support automotive stop/start and load dump condition. The TPS61193-Q1 integrates extensivefault detection features.
