TPS61193
High-Performance Three-Channel LED Driver with Integrated Boost/SEPIC Converter
The TPS61193 is a high-efficiency, low-EMI LED driver with three high-precision current sinks. It supports an integrated DC-DC converter that can operate in boost or SEPIC mode, featuring adaptive output voltage control based on LED current sink headroom to minimize power consumption. It features a wide input voltage range of 4.5V to 40V and supports a PWM dimming ratio of 10,000:1 at 100 Hz. The device includes spread spectrum switching and external synchronization to reduce EMI, along with extensive fault detection for open/shorted LEDs and thermal shutdown.
