TPS54218RTET TI DC-DC Converter | 16-WQFN (3x3) | 4.5V-28V Input, 2A Output

Product Overview

The TPS54218RTET is a high-performance, 2A step-down (buck) DC-DC converter from Texas Instruments. It integrates a high-side and low-side MOSFET with a typical on-resistance of 100mΩ and 70mΩ respectively, enabling high efficiency up to 95%. The device operates over a wide input voltage range of 4.5V to 28V, making it suitable for a variety of applications from industrial to automotive. The output voltage is adjustable from 0.8V to 0.9×VIN, with a switching frequency of 700kHz (typical). Housed in a compact 16-pin WQFN (3x3mm) package, it is ideal for space-constrained designs.
