TPS61193 Low-EMI 3-Channel LED Driver
Texas Instruments TPS61193 Low-EMI 3-Channel LED Driver is a high-efficiency, low-EMI, easy-to-use LED driver with flexibility to support a wide range of applications. It has three high-precision current sinks that can be combined for higher current capability per LED string. The device provides high dimming ratio 10.000: 1 for up to 200Hz input PWM frequency. The TPS61193 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 a dedicated pin.
