High-Efficiency White LED Driver — integrates 40V switch MOSFET and PWM dimming for portable devices, LCD backlights, and high-brightness lighting applications.
Product Overview
The TPS61161DRVR from Texas Instruments is a high-efficiency boost converter designed to drive up to 10 white LEDs in series. It integrates a 40V internal MOSFET and achieves up to 95% efficiency with PWM or analog dimming control. Operating from a 2.7V–18V input range, it is ideal for battery-powered systems.Built-in protection features include soft-start, overvoltage protection, open-LED detection, and thermal shutdown.
Packaged in a compact SOT-23-6 (DRV), it delivers excellent reliability and design flexibility for space-limited lighting applications.
