Description

TPS61194PWPRQ1  is designed and developed by Texas Instruments. It is a very good performance LED lighting driver chip that integrates rich feedback of fault detection functions. It is suitable for automotive lighting systems and is an automotive-grade chip. If you want to buy the full range of original Texas Instruments chips, please contact xt-shenzhen to serve you! ! !

The TPS61194PWPRQ1 is a low electromagnetic interference (EMI) and easy-to-use automotive high-efficiency LED driver with an integrated DC-DC converter. The DC-DC converter supports boost and SEPIC modes of operation. The device features four high-precision current sinks that can be combined to increase current capability. The DC-DC converter can provide adaptive output voltage control based on the LED current sink headroom voltage. This feature minimizes power consumption by regulating the voltage to the minimum level required under all conditions. To reduce EMI, the DC-DC converter supports spread spectrum, using dedicated pins for switching frequency and external synchronization. The TPS61194PWPRQ1 has a large adjustable frequency range to avoid AM radio band interference.
