TPS542A52RJMR TI DC-DC Converter | 33-VQFN-HR(4.5X4) | 4.5V-28V Input, 2A Output

Product Overview

The TPS542A52RJMR from Texas Instruments is a high-performance, synchronous step-down DC-DC converter designed for compact power solutions. It operates over a wide input voltage range of 4.5V to 28V and delivers up to 2A of continuous output current. Housed in a 33-pin VQFN-HR package (4.5mm x 4mm), this device integrates low RDS(on) MOSFETs to achieve high efficiency and thermal performance. The TPS542A52RJMR is ideal for space-constrained applications requiring reliable power conversion with minimal external components.
