TPS60251RTWR TI LED Driver | 24-WQFN (4x4) | 2.7-5.5V Input, 1.5A Switch

Product Overview

The TPS60251RTWR is a high-efficiency, low-noise, step-up DC-DC converter from Texas Instruments, specifically designed for driving white LEDs in series. It operates from an input voltage range of 2.7V to 5.5V, making it suitable for single-cell Li-Ion or multi-cell alkaline/NiMH applications. The device integrates a 1.5A, 0.3Ω power switch and uses a fixed-frequency, current-mode PWM control scheme to regulate the output voltage. With a switching frequency of 1.2MHz, it allows the use of small external components. The TPS60251RTWR is available in a compact 24-pin WQFN (4x4mm) package, offering a space-saving solution for portable devices.
