Product Description

The TPS61194 is a high-efficiency, low-EMI, easy-to-use LED driver with flexibility to support a wide range of applications. It has four high-precision current sinks that can be combined for higher current capability.

The TPS61194 has an integrated DC-DC supporting both boost and SEPIC mode operation. The 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 lowest sufficient level in all conditions. For EMI control the DC-DC converter supports spread spectrum for switching frequency and an external synchronization with dedicated pin.

The TPS61194 has wide input voltage range from 4.5 V to 40 V for robust support of different types of applications. The TPS61194 integrates extensive fault detection features. The device supports PWM brightness dimming ratio of 10 000:1 for 100-Hz input PWM frequency.
