The TPS61194-Q1 is an automotive high-efficiency, low-EMI,
easy-to-use LED driver with integrated DC-DC converter. The DC-DC converter supports both boost and
SEPIC mode operation. The device has four high-precision current sinks that can be combined for
higher current capability.
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. For EMI reduction DC-DC supports
spread spectrum for switching frequency and an external synchronization with dedicated pin.
A wide-range adjustable frequency allows the TPS61194-Q1 to avoid
disturbance for AM radio band.
The input voltage range for the TPS61194-Q1 is from 4.5 V to 40
V to support automotive stop/start and load dump condition. The TPS61194-Q1 integrates extensive
fault detection features.
