TPS61042DRBR TI LED Driver | 8-SON(3x3) | 1.8V-6V Input, 1.5A Switch

Product Overview

The TPS61042DRBR from Texas Instruments is a high-frequency, high-efficiency boost converter with an integrated 1.5A switch, specifically designed for white LED backlighting and other lighting applications. It operates from an input voltage range of 1.8V to 6V, making it suitable for single-cell Li-Ion or multi-cell alkaline/NiMH batteries. The device uses a current-mode PWM control scheme to regulate the output current, ensuring consistent brightness across LEDs. With a switching frequency of up to 1.2MHz, it allows for small external components, reducing solution size. The TPS61042DRBR is available in a compact 8-pin SON (3x3mm) package, ideal for space-constrained designs.
