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 boost
and SEPIC mode operation. The device has three 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-rage adjustable frequency allows the TPS61193-Q1 to avoid disturbance for AM radio
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 TPS61193-Q1 integrates extensive
fault detection features.
