TPS61194-Q1 is a low electromagnetic interference (EMI) and easy to use automotive efficient LED driver integrated with DC-DC converter. DC-DC converter supports boost and SEPIC working modes. The device has four high-precision current wells that can be combined to improve current capacity.
DC-DC converter can provide adaptive output voltage control based on LED current well margin voltage. This feature can adjust the voltage to the lowest level required under all conditions, thus minimizing power consumption. To reduce EMI, the DC-DC converter supports spread spectrum for switching frequency and external synchronization using dedicated pins. With a large adjustable frequency range, TPS61194-Q1 can avoid AM radio band interference.
The input voltage range of TPS61194-Q1 is 4.5V to 40V, which supports car start/stop and sudden load drop. TPS61194-Q1 integrates rich feedback of fault detection functions.
