Shenzhen Mingjiada Electronics Co., Ltd. new and original [distribution TI] supply TPS61193PWPRQ1 low EMI, high-performance 3-channel LED driver for automotive lighting

TPS61193PWPRQ1 Product Description:

The TPS61193-Q1 is a low EMI and easy to use automotive class high efficiency LED driver with an integrated DC-DC converter. The device features three high-precision current traps that can be used in combination to increase current capability.

The DC-DC converters provide adaptive output voltage control based on the LED current trap margin voltage. This feature allows the voltage to be regulated to the lowest level that is required under all conditions, thus reducing power consumption even more. To reduce EMI, the DC-DC converters support frequency spreading for the switching frequency as well as external synchronisation using dedicated pins. With a wide range of adjustable frequencies, the TPS61193-Q1 is able to avoid interference from the AM radio band.

The TPS61193-Q1 has an input voltage range of 4.5V to 40V and supports automotive start/stop and load sags.
