Shenzhen Meiyuxin Technology Co., Ltd. 【TI Automotive Chip Agent】 Imported Original TPS61194PWPRQ1 High-Performance 4-Channel Automotive LED Driver! ! !

Product Description:

The TPS61194PWPRQ1 is a low electromagnetic interference (EMI) and easy-to-use automotive high-efficiency LED driver with integrated DC-DC converter. The DC-DC converter supports boost and SEPIC modes of operation. The device's four high-precision current sinks can be combined to increase current capability.

The TPS61194PWPRQ1 DC-DC converter provides adaptive output voltage control based on LED current sink headroom voltage. This feature minimizes power dissipation by regulating the voltage to the lowest level that is adequate under all conditions. 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, the TPS61194-Q1 avoids AM radio band interference.

The TPS61194PWPRQ1 has an input voltage range of 4.5 V to 40 V and supports automotive start/stop and load dump conditions. The TPS61194-Q1 integrates rich feedback for fault detection functions.
