The Texas Instruments TPS61161DRVTG4 is a boost converter designed to drive LEDs in series, suitable for backlight applications. It features a 2.7-V to 18-V input voltage range and a 38-V open LED protection.
This device operates at a 600-kHz fixed switching frequency, which helps reduce output ripple and improve conversion efficiency, allowing for the use of small external components. The default white LED current is set with an external sensor resistor, and the feedback voltage is regulated to 200 mV with ±2% accuracy. The LED current can be controlled using a one-wire digital interface, offering flexible brightness control.
The TPS61161DRVTG4 includes a 40-V rated integrated switch FET and built-in soft start functionality. It achieves up to 90% efficiency. The component is housed in a compact 6-WSON (2x2 mm) package, suitable for surface mount applications.
Key electrical characteristics include a 2.7V minimum input voltage and 700mA switch current. The operating temperature range is -40°C to 85°C. The device is RoHS3 compliant and has an MSL 1 rating.
