TPS61050AYZGT TI LED Driver | 12-DSBGA | 2.7-5.5V Input, 1.5A Switch

Product Overview

The TPS61050AYZGT from Texas Instruments is a high-efficiency, synchronous boost converter with integrated 1.5A switch, designed to drive up to 5 series white LEDs or provide a regulated output voltage. Housed in a compact 12-DSBGA package, it operates from a 2.7V to 5.5V input supply, making it ideal for battery-powered applications. The device features a 1.2MHz fixed switching frequency, allowing for small external components. With True Shutdown™ isolation and overvoltage protection, it ensures safe operation. The TPS61050AYZGT is optimized for LED backlighting in portable devices, but also suits general-purpose boost applications.
