The TPS54218RTER from Texas Instruments is a high-efficiency synchronous step-down (buck) DC-DC converter. It delivers up to 2A of continuous output current with an adjustable output voltage range from 0.8V to 4.5V, making it suitable for a variety of low-voltage power applications. The device operates from an input voltage range of 2.95V to 6V, and its switching frequency is programmable from 200 kHz to 2 MHz, allowing designers to trade off between efficiency and component size.
The converter integrates two 30mOhm typical MOSFETs for synchronous rectification, achieving high efficiency even at 2A loads. The quiescent current is typically 350 µA, and the maximum duty cycle reaches 98%. The voltage reference is accurate to ±1% over temperature. Protection features include overcurrent and thermal shutdown.
The TPS54218RTER is housed in a compact 16-pin WQFN (3mm x 3mm) package with an exposed pad for improved thermal performance. The operating junction temperature range is -40°C to 150°C. It is designed for surface mount assembly and is ideal for space-constrained applications requiring efficient power conversion.
