TPS62093RGTR

TPS62093RGTR Description

The TPS62093RGTR from Texas Instruments is a high-efficiency, 3A synchronous step-down (Buck) DC/DC converter designed for space-constrained and power-sensitive applications. With a fixed 1.8V output, it operates over a 2.5V to 6V input range, making it ideal for systems powered by single-cell Li-ion batteries or 3.3V/5V rails. The device integrates synchronous rectification, achieving high efficiency (up to 95%) while minimizing external component count. Its 2.8MHz switching frequency allows for compact inductor and capacitor selection, reducing PCB footprint. Packaged in a 16-pin VQFN (3mm x 3mm), it is optimized for surface-mount assembly and complies with ROHS3 and REACH environmental standards.

TPS62093RGTR Features

• High Efficiency: Synchronous rectification and low RDS(on) MOSFETs ensure minimal power loss.
• Compact Design: 2.8MHz switching frequency enables tiny passive components, ideal for portable devices.
• Wide Input Range: 2.5V–6V supports diverse power sources, including batteries and regulated rails.
